Definitions
- the present invention relates generally to sighting systems for precisely aligning a device, such as a firearm or telescope, with a target. More specifically, embodiments of the present invention concern a firearm sighting system with proximal and distal sights that present a sight picture when viewed with complementally shaped surfaces.
- Prior art metallic gun sights include peep sights and open sights. Both peep sights and open sights utilize a proximal or rear sight, i.e., nearest the user's eye, in cooperation with a distal or front sight, i.e., spaced along the firearm in a direction away from the user.
- Peep sights generally have an aperture in the rear sight and the front sight commonly includes a blade, a post and bead, a circle, or a circle and insert.
- the rear aperture is typically positioned close to the shooter's eye, which in the sight picture surrounds, and is larger than, the front sight.
- Open sights traditionally are post and notch, where the front sight is a post or blade and the rear sight includes a blade with a notch.
- the rear sight in open sights is typically viewed from a distance in operation.
- peep sights are problematic and subject to several undesirable limitations.
- open sights and peep sights lack precision for fine accuracy.
- the aiming references of open sights are limited to the two symmetrical blocks of light in the rear sight on either side of the front sight post, and the alignment of the top edges of the front blade with the rear sight.
- Peep sights include a rear sight with an aperture close to the shooter's eye, wherein the user looks through the aperture to view the front sight.
- the aperture provides a much larger sighting surface that encircles a relatively small sighting surface of the front sight.
- the substantial radial spacing between the sights when viewed provides an aiming reference that is imprecise.
- the centering of the front bead or blade inside the rear sight aperture provides the only aiming reference between the two sights.
- the rear sight of a peep sight commonly has large eye discs and relatively bulky metal close to the shooter's eye and face.
- the rear sight substantially blocks the user's view of the target area except for the aperture.
- a rear sight obscures the target, particularly when the user has not yet acquired the target.
- the rear sight obscures the front sight.
- the rear sight of an open sight necessarily obscures a large portion of the front sight when the sights are perfectly aligned. Prior to perfect alignment, the rear sight can easily entirely block the user's view of the front sight. Similarly, the rear sight of a peep sight can also obscure the front sight prior to alignment of the sights.
- prior art rear sights such as those of an open or peep sight, block a substantial part of the user's view. Consequently, prior art rear sights do not allow sufficient light to pass through to the user, particularly in low light conditions.
- the present invention provides a sighting assembly that does not suffer from the problems and limitations of the prior art gun sights set forth above.
- a first aspect of the present invention concerns a firearm sighting assembly for facilitating aiming of a firearm at a target by a user.
- the firearm sighting assembly broadly includes proximal and distal sights configured for connection to the firearm to sight the target along a sighting direction.
- the proximal sight is connectable to the firearm closer to the user along the sighting direction than the distal sight.
- the distal sight presents a generally inward facing distal sighting surface that defines an opening.
- the proximal sight presents a generally outward facing proximal sighting surface.
- the proximal sighting surface is spaced within the opening when the target is viewed with the sights, such that the sighting surfaces present corresponding opposed sections when viewed.
- the proximal and distal sighting surfaces present respective radial dimensions measured relative to the sighting direction.
- the proximal sighting surface is radially smaller than the distal sighting surface along the corresponding opposed sections.
- a second aspect of the present invention concerns a firearm assembly operable by a user to aim at a target.
- the firearm assembly broadly includes a firearm and a firearm sighting assembly.
- the firearm includes a muzzle end.
- the firearm sighting assembly facilitates aiming of the firearm at the target.
- the firearm sighting assembly includes proximal and distal sights connected to the firearm to sight the target along a sighting direction, with the distal sight being spaced closer to the muzzle end than the proximal sight.
- the distal sight presents a generally inward facing distal sighting surface that defines an opening.
- the proximal sight presents a generally outward facing proximal sighting surface.
- the proximal sighting surface is spaced within the opening when the target is viewed with the sights, such that the sighting surfaces present corresponding opposed sections when viewed.
- the proximal and distal sighting surfaces present respective radial dimensions measured relative to the sighting direction.
- the proximal sighting surface is radially smaller than the distal sighting surface along the corresponding opposed sections.

- the inventive sighting assembly 20 is configured to provide superior accuracy, faster target acquisition, and improved low light capability for a shooter aiming the firearm H at a target and broadly includes a muzzle sight 22 and a breech sight 24 .
- the illustrated muzzle sight 22 broadly includes a base 26 , a body 28 coupled to the base 26 , and an insert 30 removably coupled to the body 28 .

- the surfaces 42 , 44 are configured for sighting a target.
- the illustrated body 28 is preferably cylindrical and includes internal threads 46 adjacent the proximal end 38 .
- the insert 30 includes a cylindrical body 48 and presents a proximal end 50 and an externally threaded distal end 52 .
- the bodies 28 , 48 are preferably cylindrical and, therefore, have a circular cross section, it is also within the ambit of the present invention where the bodies 28 , 48 have a cross section comprising other geometrical shapes, e.g., a semicircle, a polygon, or another suitable shape.
- the insert 30 Adjacent the end 50 , the insert 30 includes an outer circular element 54 , an inner circular element 56 , and cross hair portions 60 that are integrally formed with the body 48 .

As will be discussed in greater detail, surfaces 42 , 44 , 62 , 64 , 66 cooperate with surfaces of the breech sight 24 to define a sight picture of the sighting assembly 20 , i.e., a user's view of the silhouette formed by the sighting assembly 20 when aiming the handgun H at the target.
- the insert 30 is threadably inserted within the body 28 so that the threaded distal end 52 is received by the internal threads 46 .
- the thickness of the outer circular element 54 is substantially the same as the thickness of the barrel-shaped body 28 .
- the principles of the present invention are equally applicable where the outer circular element 54 is thicker than the body 28 so as to present a correspondingly thicker circular silhouette form for the muzzle sight 22 .
- the muzzle sight 22 is adjustable to accommodate several variables such as environmental conditions (e.g., lighting or terrain) and the user's visual acuity.
- the illustrated breech sight 24 is a flip-up sight and is mounted adjacent the proximal end Ep.
- the breech sight 24 broadly includes an adjustable sight base 68 , a windage platform 70 , and a shiftable dual sight 72 .
- the sight base 68 is preferably comprised of spring steel and the remainder of the breech sight 24 is preferably comprised of SAE 4140 carbon steel. However, it is within the ambit of the present where the breech sight 24 is manufactured from other carbon steels, aluminum, stainless steel, or other suitable metallic or non-metallic materials.
- the sight base 68 includes an elongated bracket 74 with proximal and distal ends 76 , 78 .

- the distal screw 84 is threaded fully into the handgun H.
- the proximal screw 82 is preferably adjustable to position the proximal end 76 vertically relative to the handgun H. With the proximal screw 82 removed and the distal screw 84 installed, the proximal end 76 is spaced from an uppermost surface of the handgun H, due to the configuration of the angled tab 80 . The installation of proximal screw 82 permits the proximal end 76 to be vertically repositioned at a distance from the uppermost surface from about zero inches to about 3/16 inch. The construction of the bracket 74 with spring steel permits the bracket 74 to elastically bend as the proximal screw 82 is threaded into the handgun H. As will be discussed, vertical positioning of the screw 82 permits selective vertical positioning of the dual sight 72 .
- the sight base 68 further includes a pedestal 86 integrally formed with the bracket 74 adjacent the distal end 78 and a catch 88 slidably attached to an uppermost surface of the pedestal 86 (see FIG. 2 ).

- the spirit level 108 is similar to those known in the art and, in the usual manner, includes an outer shell preferably comprising a high-impact cast acrylic and contains a liquid and a gas bubble 110 floating in the liquid (see FIG. 3 ).
- the spirit level 108 indicates orientation of the handgun H and is particularly suitable for repetitively positioning the handgun H prior to firing. It has been determined that such repeatability in firearm positioning is critical for maintaining accuracy in long range shooting applications, particularly with a handgun such as the illustrated handgun H.
- the windage platform 70 is attached to the sight base 68 by extending the windage screw 94 through coaxial holes 92 and through-hole 102 .
- the windage screw 94 includes external threads that engage the internal threads of the through-hole 102 . Rotational movement of the windage screw 94 shifts the windage platform 70 relative to the sight base 68 laterally along the axis of the windage screw 94 and between the bosses 90 .

- the insert 118 is threadably inserted within the body 116 .
- the thickness of the circular element 130 is substantially the same as the thickness of the cylindrical body 116 .
- the principles of the present invention are equally applicable where the circular element 130 is thicker than the body 116 so as to present a correspondingly thicker silhouette form for the breech sight 24 . In this manner, the breech sight 24 is adjustable to accommodate variable conditions as discussed previously with respect to the muzzle sight 22 .
- the long-range sight 114 preferably includes a staff 134 , a shiftable sight 136 , and an elevation screw 138 .

- the sight 136 is shifted by the screw 138 in the corresponding direction along the staff 134 .
- the short-range sight 112 is integrally fixed to the long-range sight 114 .
- the short-range sight 112 generally extends at a right angle to the long-range sight 114 , so that only one of the sights 112 , 114 is configured for use at a particular time.
- the dual sight 72 is shiftably attached to the sight base 68 by the pin 106 .
- the dual sight 72 is shiftable relative to the sight base 68 about an axis of the pin 106 to position either the short-range sight 112 or the long-range sight 114 into an upright sighting position.

- the long-range sight 114 is shifted into a lowered position and extends laterally along the bracket 74 , i.e., the short-range sighting configuration.
- the dual sight 72 is secured in this lowered position by shifting the catch 88 rearwardly into a staff engagement position (shown in FIG. 5 ).
- the catch 88 is configured to shift forwardly (as shown in FIG. 2 ). Subsequently, the dual sight 72 is rotatable about the pin 106 in a generally rearward direction until the short-range sight 112 contacts the windage platform 70 and the long-range sight 114 is placed into the upright sighting position, i.e., a long-range sighting configuration.

- the windage platform 70 shifts relative to the sight base 68 laterally along the axis of the windage screw 94 . Consequently, the dual sight 72 is shifted by the windage platform 70 along the lateral axis and relative to the muzzle sight 22 .
- the sight base 68 is vertically adjustable by adjustment of the proximal screw 82 .
- the proximal screw 82 is repositioned accordingly while the screw 84 remains fully threaded in the handgun H.
- the proximal screw 82 is threaded out of the handgun H and the distal screw 84 remains threaded in the handgun H.
- the sight base 68 can be repositioned by adjustment of the screw 82 as discussed.
- the shiftable sight 136 can be vertically adjusted by rotating the elevation screw 138 .
- either of the sights 112 , 114 are adjustable both vertically and laterally relative to the muzzle sight 22 .

While the illustrated embodiment preferably includes various aiming windows, it is also within the ambit of the present invention where other types of openings or apertures are formed by one or more of the above referenced sighting surfaces.
- the sights 22 , 24 preferably present a sight picture or silhouette form comprising three (3) substantially concentric circles. Furthermore, the sight picture includes perpendicular cross hairs that extend from the outermost circle to the innermost circle. More preferably, the breech sight 24 provides the intermediate circle of the three circles.

- the illustrated embodiment preferably includes aiming windows 160 , 162 , 164 to create this vivid sight picture, the principles of the present invention are applicable where a large number of other types of apertures or openings are grouped together to provide a sight picture.
- the use of concentric, closely-spaced sighting surfaces creates narrow aiming windows that precisely indicate any misalignment of the sights 22 , 24 to the user.
- the aiming windows 160 , 162 , 164 present an unobstructed space for viewing a target with at least one width dimension transverse to any axis of misalignment.
- the width dimension is shorter than a length dimension of the window 160 , 162 , 164 , although the principles of the present invention are applicable where the width has the same or larger dimension than the length.

- the user can selectively shift the dual sight 72 into either a long-range or short-range configuration (i.e., with either the long-range sight 114 or the short-range sight 112 in the upright sighting position).
- the sights 22 , 24 are configured to be viewed so as to be coaxial with one another to define the sighting axis A and thereby provide a sight picture as discussed above.
- the spirit level 108 is operable to provide an indication of handgun orientation to the user.
- FIGS. 8-16 alternative preferred embodiments of the present invention are depicted. For the sake of brevity, the remaining description will focus primarily on the differences of these alternative embodiments from the preferred embodiment described above.

Abstract
A sighting assembly is configured for use on a firearm in long-range sighting applications and broadly comprises proximal and distal sights. The sights present various sighting surfaces including at least a pair of complemental surfaces that, when viewed along a sighting direction, are opposed to one another. The distal sight presents a radially outer one of the opposed sighting surfaces and the proximal sight presents a radially inner one of the opposed sighting surfaces. The opposed surfaces cooperatively present at least one aiming window for accurately aligning the sights and viewing a target.
Description
- 1. Field of the Invention
- The present invention relates generally to sighting systems for precisely aligning a device, such as a firearm or telescope, with a target. More specifically, embodiments of the present invention concern a firearm sighting system with proximal and distal sights that present a sight picture when viewed with complementally shaped surfaces.
- 2. Discussion of Prior Art
- Metallic gun sights, also known as “iron sights,” are known in the art. Prior art metallic gun sights include peep sights and open sights. Both peep sights and open sights utilize a proximal or rear sight, i.e., nearest the user's eye, in cooperation with a distal or front sight, i.e., spaced along the firearm in a direction away from the user. Peep sights generally have an aperture in the rear sight and the front sight commonly includes a blade, a post and bead, a circle, or a circle and insert. The rear aperture is typically positioned close to the shooter's eye, which in the sight picture surrounds, and is larger than, the front sight. Open sights traditionally are post and notch, where the front sight is a post or blade and the rear sight includes a blade with a notch. The rear sight in open sights is typically viewed from a distance in operation.
- All prior art metallic gun sights, including peep sights and open sights, are problematic and subject to several undesirable limitations. For example, open sights and peep sights lack precision for fine accuracy. The aiming references of open sights are limited to the two symmetrical blocks of light in the rear sight on either side of the front sight post, and the alignment of the top edges of the front blade with the rear sight. Peep sights include a rear sight with an aperture close to the shooter's eye, wherein the user looks through the aperture to view the front sight. Typically when viewed, the aperture provides a much larger sighting surface that encircles a relatively small sighting surface of the front sight. The substantial radial spacing between the sights when viewed provides an aiming reference that is imprecise. Furthermore, the centering of the front bead or blade inside the rear sight aperture provides the only aiming reference between the two sights.
- Another limitation of prior art sights, including open sights and peep sights, is that they obscure the target during aiming. With respect to open sights, the user must cut the target, such as a black circle bulls eye, in half with the rear blade in order to aim at the center of the target. The solid rear blade necessarily obscures the user's view of at least half of the target when aiming perfectly at the center. The rear blade also obscures the target when the user has not yet acquired the target, e.g., where the target is spaced below the upper edge of the blade. The alternative method of aiming with an open sight is to float the entire target above the blade, which is an inherently imprecise way of aiming at the center of the target. Similarly, the rear sight of a peep sight commonly has large eye discs and relatively bulky metal close to the shooter's eye and face. During aiming, the rear sight substantially blocks the user's view of the target area except for the aperture. Thus, a rear sight obscures the target, particularly when the user has not yet acquired the target.
- Yet another limitation of prior art sights is that the rear sight obscures the front sight. For example, the rear sight of an open sight necessarily obscures a large portion of the front sight when the sights are perfectly aligned. Prior to perfect alignment, the rear sight can easily entirely block the user's view of the front sight. Similarly, the rear sight of a peep sight can also obscure the front sight prior to alignment of the sights.
- As mentioned, prior art rear sights, such as those of an open or peep sight, block a substantial part of the user's view. Consequently, prior art rear sights do not allow sufficient light to pass through to the user, particularly in low light conditions.
- Thus, all prior art metallic gun sights continue to suffer from several basic problems: the sight picture to the shooter does not provide precise aiming references, prior art sights obscure the target and surrounding target areas, the rear sight obscures the front sight, and target acquisition is poor in low light. These limitations of prior art sights also tend to slow target acquisition. Accordingly, there is a need for an improved sighting system.
- The present invention provides a sighting assembly that does not suffer from the problems and limitations of the prior art gun sights set forth above.
- A first aspect of the present invention concerns a firearm sighting assembly for facilitating aiming of a firearm at a target by a user. The firearm sighting assembly broadly includes proximal and distal sights configured for connection to the firearm to sight the target along a sighting direction. The proximal sight is connectable to the firearm closer to the user along the sighting direction than the distal sight. The distal sight presents a generally inward facing distal sighting surface that defines an opening. The proximal sight presents a generally outward facing proximal sighting surface. The proximal sighting surface is spaced within the opening when the target is viewed with the sights, such that the sighting surfaces present corresponding opposed sections when viewed. The proximal and distal sighting surfaces present respective radial dimensions measured relative to the sighting direction. The proximal sighting surface is radially smaller than the distal sighting surface along the corresponding opposed sections.
- A second aspect of the present invention concerns a firearm assembly operable by a user to aim at a target. The firearm assembly broadly includes a firearm and a firearm sighting assembly. The firearm includes a muzzle end. The firearm sighting assembly facilitates aiming of the firearm at the target. The firearm sighting assembly includes proximal and distal sights connected to the firearm to sight the target along a sighting direction, with the distal sight being spaced closer to the muzzle end than the proximal sight. The distal sight presents a generally inward facing distal sighting surface that defines an opening. The proximal sight presents a generally outward facing proximal sighting surface. The proximal sighting surface is spaced within the opening when the target is viewed with the sights, such that the sighting surfaces present corresponding opposed sections when viewed. The proximal and distal sighting surfaces present respective radial dimensions measured relative to the sighting direction. The proximal sighting surface is radially smaller than the distal sighting surface along the corresponding opposed sections.

FIG. 1 illustrates asighting assembly 20 constructed in accordance with a preferred embodiment of the present invention and configured for mounting on a handgun H. As will be further detailed below, the illustratedsighting assembly 20 is particularly well suited for facilitating target acquisition in relatively long range applications where precise accuracy is valued. One such application is competitive long range target shooting, such as traditional bulls eyes at distances as far as one-thousand yards. Accordingly, the handgun H illustrated inFIG. 1 is suitable for such applications, such as a large caliber handgun. However, the principles of the present invention are not limited to any particular type of firearm and would equally apply to any weapon where a metal sight is utilized, such as a civilian or military handgun, rifle, shotgun, crossbow and the like. Furthermore, while the principles of the present invention are well suited for metallic gun sight applications, they can be equally applied to any device that needs to be precisely aligned with a location, such as a telescope. - The illustrated handgun H is a conventional Smith and Wesson revolver-type handgun and broadly includes a frame F, a grip G, a barrel B coupled to the frame F, and hardware HW associated with the frame F for firing ammunition through the barrel B. The frame F, barrel B, and hardware HW comprise the traditional components of any conventional handgun and accordingly will not be described in detail herein with the understanding that these components could be variously configured in any manner well known in the art. The illustrated hardware HW includes a revolving, multiple-chamber cylinder C with a hammer and trigger firing mechanism. The handgun H also presents a distal end Ed (i.e., the muzzle end of the handgun H spaced distally from the user) and a proximal end Ep (i.e., the breech end of the handgun H spaced proximally to the user).
- Turning now to
FIGS. 1-7 , theinventive sighting assembly 20 is configured to provide superior accuracy, faster target acquisition, and improved low light capability for a shooter aiming the firearm H at a target and broadly includes amuzzle sight 22 and abreech sight 24. Perhaps as best shown inFIGS. 1 , 2, and 7, the illustratedmuzzle sight 22 broadly includes abase 26, abody 28 coupled to thebase 26, and aninsert 30 removably coupled to thebody 28. Themuzzle sight 22 is preferably comprised of SAE 4140 carbon steel. However, it is within the ambit of the present where themuzzle sight 22 is manufactured from other carbon steels, aluminum, stainless steel, or other suitable metallic or non-metallic materials. - In more detail, the
base 26 is configured to mount on the handgun H atop the distal end Ed of the barrel B. In one manner well known in the art, thebase 26 is attached to aramp portion 32 of the barrel B and includes aninset portion 34 that is coupled to theramp portion 32. Each of theportions ramp portion 32 is preferably integrally formed with the barrel B, the principles of the present invention are applicable where theramp portion 32 is otherwise affixed thereto, such as with screws, pins, weldment, or the like. Theinset portion 34 interlocks with theramp portion 32 and once interlocked, could be removably coupled thereto (e.g., by a press fit or pinned joint) or permanently coupled thereto (e.g., by a weldment). The illustratedinset 34 includes a steppedsetoff 36 adjacent a proximate end of theinset portion 34. The base 16 could be variously alternatively configured in any suitable manner known in the art. For example, the base 26 need not be a two-piece configuration. Additionally, thebase 26 could be eliminated altogether, such as affixing thebody 28 directly to the barrel B. However, if abase 26 is utilized, thebase 26 is preferably coupled to the handgun H centered atop the barrel B adjacent the distal end Ed. - The
body 28 is coupled to thebase 26 and is configured to receive theinsert 30 to cooperatively present proximal and distal open ends 38,40 of themuzzle sight 22 and internal and external sighting surfaces 42,44 that are preferably substantially coaxial between theends surfaces body 28 is preferably cylindrical and includesinternal threads 46 adjacent theproximal end 38. Theinsert 30 includes acylindrical body 48 and presents aproximal end 50 and an externally threadeddistal end 52. While thebodies bodies end 50, theinsert 30 includes an outercircular element 54, an innercircular element 56, andcross hair portions 60 that are integrally formed with thebody 48. Theinner element 56 is spaced within the outercircular element 54, withcross hair portions 60 interconnecting the innercircular element 56 and the outercircular element 54. - The inner
circular element 56 presents internal and external sighting surfaces 62,64, which are preferably coaxial. Thecross hair portions 60 present sighting surfaces 66. Similar tosurfaces breech sight 24 to define a sight picture of thesighting assembly 20, i.e., a user's view of the silhouette formed by thesighting assembly 20 when aiming the handgun H at the target. - The
insert 30 is threadably inserted within thebody 28 so that the threadeddistal end 52 is received by theinternal threads 46. The thickness of the outercircular element 54 is substantially the same as the thickness of the barrel-shapedbody 28. However, the principles of the present invention are equally applicable where the outercircular element 54 is thicker than thebody 28 so as to present a correspondingly thicker circular silhouette form for themuzzle sight 22. In this manner, themuzzle sight 22 is adjustable to accommodate several variables such as environmental conditions (e.g., lighting or terrain) and the user's visual acuity. - The illustrated
breech sight 24 is a flip-up sight and is mounted adjacent the proximal end Ep. Thebreech sight 24 broadly includes anadjustable sight base 68, awindage platform 70, and a shiftabledual sight 72. Thesight base 68 is preferably comprised of spring steel and the remainder of thebreech sight 24 is preferably comprised of SAE 4140 carbon steel. However, it is within the ambit of the present where thebreech sight 24 is manufactured from other carbon steels, aluminum, stainless steel, or other suitable metallic or non-metallic materials. - Turning to
FIGS. 4-7 , thesight base 68 includes anelongated bracket 74 with proximal and distal ends 76,78. Thebracket 74 includes anangled tab 80 adjacent thedistal end 78. Again, thebracket 74 is preferably made of spring steel and is, therefore, is elastically bendable. Thebracket 74 further includes proximal anddistal screws bracket 74 and which secure thebracket 74 to the handgun H. Thedistal screw 84 is threaded into the handgun H to position theangled tab 80 firmly against the handgun H. Preferably, thedistal screw 84 is threaded fully into the handgun H. However, it is consistent with the principles of the present invention where thedistal screw 84 is adjustably threaded into the handgun H. - The
proximal screw 82 is preferably adjustable to position theproximal end 76 vertically relative to the handgun H. With theproximal screw 82 removed and thedistal screw 84 installed, theproximal end 76 is spaced from an uppermost surface of the handgun H, due to the configuration of theangled tab 80. The installation ofproximal screw 82 permits theproximal end 76 to be vertically repositioned at a distance from the uppermost surface from about zero inches to about 3/16 inch. The construction of thebracket 74 with spring steel permits thebracket 74 to elastically bend as theproximal screw 82 is threaded into the handgun H. As will be discussed, vertical positioning of thescrew 82 permits selective vertical positioning of thedual sight 72. - The
sight base 68 further includes apedestal 86 integrally formed with thebracket 74 adjacent thedistal end 78 and acatch 88 slidably attached to an uppermost surface of the pedestal 86 (seeFIG. 2 ). The sight base also includesbosses 90 adjacent the proximal end 60 (seeFIG. 6 ), withcoaxial holes 92 therethrough, and awindage screw 94 rotatably received within theholes 92 and configured to position thewindage platform 70, as will be discussed. - The
windage platform 70 includes abody 96 that presents alower base 98 andconnectors 100 projecting from thebase 98. Thelower base 98 includes a threaded through-hole 102 for receiving thewindage screw 94, as will be discussed.Coaxial holes 104 extend through theconnectors 100 to receive apin 106. Thewindage platform 70 further includes aspirit level 108 attached to and spaced within thebody 96. Thespirit level 108 is similar to those known in the art and, in the usual manner, includes an outer shell preferably comprising a high-impact cast acrylic and contains a liquid and agas bubble 110 floating in the liquid (seeFIG. 3 ). Thespirit level 108 indicates orientation of the handgun H and is particularly suitable for repetitively positioning the handgun H prior to firing. It has been determined that such repeatability in firearm positioning is critical for maintaining accuracy in long range shooting applications, particularly with a handgun such as the illustrated handgun H. - The
windage platform 70 is attached to thesight base 68 by extending thewindage screw 94 throughcoaxial holes 92 and through-hole 102. Thewindage screw 94 includes external threads that engage the internal threads of the through-hole 102. Rotational movement of thewindage screw 94 shifts thewindage platform 70 relative to thesight base 68 laterally along the axis of thewindage screw 94 and between thebosses 90. - The
dual sight 72 broadly includes a short-range sight 112 and a long-range sight 114 integrally attached to one another. The short-range sight 112 comprises acylindrical body 116 similar to thebody 28 and aninsert 118. Thebody 116 and insert 118 cooperatively present proximal and distal open ends 120,122 and internal and external sighting surfaces 124,126 that preferably substantially extend coaxially between theends surfaces sighting assembly 20. - The
body 116 is cylindrical and includesinternal threads 128 adjacent theproximal end 120. Theinsert 118 is unitary and includes acircular element 130 and a threadedelement 132. Theinsert 118 is threadably inserted within thebody 116. In the illustrated embodiment, the thickness of thecircular element 130 is substantially the same as the thickness of thecylindrical body 116. However, the principles of the present invention are equally applicable where thecircular element 130 is thicker than thebody 116 so as to present a correspondingly thicker silhouette form for thebreech sight 24. In this manner, thebreech sight 24 is adjustable to accommodate variable conditions as discussed previously with respect to themuzzle sight 22. - The long-
range sight 114 preferably includes astaff 134, ashiftable sight 136, and anelevation screw 138. Thestaff 134 is a preferably unitary metallic plate and presents anopening 140. Thesight 136 is also preferably a unitary metallic plate and comprises aU-shaped frame 142 and acircular element 144 that is preferably fixed to and spaced within theframe 142. Thecircular element 144 preferably includes internal and external sighting surfaces 146,148 that coaxially extend between proximal anddistal ends FIG. 2 ). Similar tosurfaces surfaces sighting assembly 20. - In addition, the
shiftable sight 136 andwindage platform 70 present other sighting surfaces 154 (seeFIG. 6 ). However, the principles of the present invention are applicable where other portions of the sighting assembly 10 present sighting surfaces for sighting a target. - The
sight 136 is preferably slidably mounted on thestaff 134. Theelevation screw 138 includes ahead 156 and ascrew body 158 and is rotatably mounted on thestaff 134. Thescrew 138 also extends through a threaded bore (not shown) of thesight 136. Thus, as thehead 156 is rotated thesight 136 is shifted by thescrew 138 in the corresponding direction along thestaff 134. - As previously mentioned, the short-
range sight 112 is integrally fixed to the long-range sight 114. In particular, the short-range sight 112 generally extends at a right angle to the long-range sight 114, so that only one of thesights - The
dual sight 72 is shiftably attached to thesight base 68 by thepin 106. Thedual sight 72 is shiftable relative to thesight base 68 about an axis of thepin 106 to position either the short-range sight 112 or the long-range sight 114 into an upright sighting position. When the short-range sight 112 is placed into the upright sighting position (seeFIG. 5 ), the long-range sight 114 is shifted into a lowered position and extends laterally along thebracket 74, i.e., the short-range sighting configuration. Furthermore, thedual sight 72 is secured in this lowered position by shifting thecatch 88 rearwardly into a staff engagement position (shown inFIG. 5 ). To permit shifting of the short-range sight 112 out of the first sighting position, thecatch 88 is configured to shift forwardly (as shown inFIG. 2 ). Subsequently, thedual sight 72 is rotatable about thepin 106 in a generally rearward direction until the short-range sight 112 contacts thewindage platform 70 and the long-range sight 114 is placed into the upright sighting position, i.e., a long-range sighting configuration. In the long-range configuration, thedual sight 72 is preferably frictionally held in place. - For relative lateral shifting between the
sights windage platform 70 andwindage screw 94 cooperate to shift thedual sight 72 relative to thesight base 68. Thus, as thewindage screw 94 is rotated, thewindage platform 70 shifts relative to thesight base 68 laterally along the axis of thewindage screw 94. Consequently, thedual sight 72 is shifted by thewindage platform 70 along the lateral axis and relative to themuzzle sight 22. - As previously discussed, the
sight base 68 is vertically adjustable by adjustment of theproximal screw 82. Thus, in order to adjust the vertical position of the short-range sight 112 relative to themuzzle sight 22, theproximal screw 82 is repositioned accordingly while thescrew 84 remains fully threaded in the handgun H. For example, in order to raise the short-range sight 112, theproximal screw 82 is threaded out of the handgun H and thedistal screw 84 remains threaded in the handgun H. - For vertical adjustment of the long-
range sight 114, thesight base 68 can be repositioned by adjustment of thescrew 82 as discussed. In addition, theshiftable sight 136 can be vertically adjusted by rotating theelevation screw 138. Thus, either of thesights muzzle sight 22. - Turning to

Furthermore, aimingwindows - Thus, the
sights breech sight 24 provides the intermediate circle of the three circles. That is, themuzzle sight 22 presents the innermost and outermost circles with thebreech sight 24 presenting a circle that is spaced within the outermost circle and itself encircles the innermost circle. This configuration of sighting surfaces between thesights sighting assembly 20 includes other forms and configurations of geometric surfaces. - In the illustrated embodiment, an upper pair of the aiming

The uniformity of the aimingwindows windows windows - Furthermore, the use of concentric, closely-spaced sighting surfaces creates narrow aiming windows that precisely indicate any misalignment of the
sights windows window sights - While the
sighting assembly 20 does not include optical magnification therein, the principles of the present invention are applicable where a magnification lens is included in one or both of thesights respective body insert - In operation, the handgun H is preferably held by a user so that the illustrated
sighting assembly 20 is positioned from the user at a sight relief distance of about eighteen (18) inches. The sight relief distance is the distance from the user's eye to the most proximal sight, i.e., thebreech sight 24. The user can selectively shift thedual sight 72 into either a long-range or short-range configuration (i.e., with either the long-range sight 114 or the short-range sight 112 in the upright sighting position). Thesights spirit level 108 is operable to provide an indication of handgun orientation to the user. - Turning to
