## Title
Modular scope mount assembly

## Abstract

Implementations of a modular scope mount assembly are provided. In some implementations, the modular scope mount assembly may be used to secure a telescopic sight to a firearm (e.g., a rifle and/or a carbine). In some implementations, the modular scope mount assembly may be used to co-mount a telescopic sight and a reflex sight to a firearm. In some implementations, the modular scope mount assembly may be configured to place a reflex sight on the right side and/or left side of a co-mounted telescopic sight. In some implementations, the modular scope mount assembly may be configured to allow a user to change (increase or decrease) the eye relief between the user and the co-mounted reflex sight(s).

## Background
CROSS REFERENCE TO RELATED APPLICATION
This application claims the benefit of U.S. patent application Ser. No. 62/104,323, which was filed on Jan. 16, 2015, and is incorporated herein by reference in its entirety.


TECHNICAL FIELD
This disclosure relates to implementations of a modular scope mount assembly.
BACKGROUND
Telescopic sights and reflex sights are two sighting systems routinely used to aim a firearm. In general, telescopic sights are used to improve long range accuracy with a firearm while reflex sights are used at short range for rapid acquisition of and transitions between targets. Many shooters (e.g., warfighters or mult gun competitors) find it advantageous to mount both a telescopic sight and a reflex sight on their rifle. A rifle equipped with both telescopic and reflex sights allows the shooter to rapidly transition between a sighting system optimized for long range engagements and a sighting system optimized for short range engagements.
A variety of mounting options have been developed to facilitate the co-attachment of both a telescopic sight and a reflex sight to a firearm. Typically, a mount comprising a base and rings is used to secure a telescopic sight to the receiver of a firearm and a second mount configured to secure about the tube portion of the telescopic sight is used to secure the reflex sight thereto. In some instances, the second mount may be rotated about the tube portion of the telescopic sight to thereby position the reflex sight on the right or left side of the telescopic sight.
However, these mounting options have several disadvantages. First, the user may not be able to maintain a cheek weld when using the co-mounted reflex sight. This can affect the shooters ability to deliver accurate aimed fire using the reflex sight. Second, the distance between the co-mounted reflex sight and the bore of the firearm will cause there to be a significant difference between the parabolic travel path of a bullet fired from the firearm and the aiming point of the reflex sight. This can negatively affect the shooters ability to rapidly make precise shots at short range using the reflex sight.
SUMMARY OF THE INVENTION
Implementations of a modular scope mount assembly are provided. In some implementations, the modular scope mount assembly may be used to secure a telescopic sight to a firearm (e.g., a rifle and/or a carbine). In some implementations, the modular scope mount assembly may be used to co-mount a telescopic sight and a reflex sight to a firearm. In some implementations, the modular scope mount assembly may be configured to place a reflex sight on the right side and/or left side of a co-mounted telescopic sight. In some implementations, the modular scope mount assembly may be configured to allow a user to change (increase or decrease) the eye relief between the user and the co-mounted reflex sight(s).
In some implementations, the modular scope mount assembly may comprise a first base, a second base, a bridge, a first scope ring, and a second scope ring. In some implementations, the modular scope mount assembly may further comprise an offset adaptor plate to which a reflex sight can be mounted.
In some implementations, the bridge may be removably secured to the first base and the second base. In some implementations, one base may include an offset mounting surface to which the adaptor plate is secured. In some implementations, the bridge may be configured to increase the usable elevation (or vertical) adjustment range of a telescopic sight mounted to the modular scope mount assembly. In some implementations, the first scope ring and the second scope ring may be removably secured to the bridge.

DETAILED DESCRIPTION
FIGS. 1A-1B, 2A-2B, 3A-3B, and 4-5 illustrate an example modular scope mount assembly 100 according to the present disclosure. In some implementations, the modular scope mount assembly 100 may be used to secure a telescopic sight 230 to a firearm (e.g., a rifle and/or a carbine). In some implementations, the modular scope mount assembly 100 may be used to co-mount a telescopic sight 230 and a reflex sight 250 to a firearm (see, e.g., FIG. 5).
As shown in FIGS. 1A-1B, in some implementations, the modular scope mount assembly 100 may comprise a first base 105a, a second base 105b (collectively bases 105), a bridge 115, a first scope ring 125a, and a second scope ring 125b (collectively scope rings 125). In some implementations, the modular scope mount assembly 100 may further comprise an adaptor plate 150 to which a reflex sight 250 can be mounted (see, e.g., FIG. 5). In some implementations, the bridge 115 may be removably secured to the first base 105a and the second base 105b (see, e.g., FIG. 2A). In some implementations, the first scope ring 125a, and the second scope ring 125b may be removably secured to the bridge 115 (see, e.g., FIGS. 1A and 2A).
As shown in FIG. 3B, in some implementations, the first base 105a and the second base 105b each have a bottom side 107a, 107b (collectively bottom sides 107), respectively. In some implementations, the bottom side 107a, 107b of each base 105a, 105b may be configured to fit about a portion of a Picatinny rail 205 and secured thereto through the use of a clamp 111a, 111b (collectively clamps 111), respectively (see, e.g., FIG. 4). In some implementations, a clamp 111a, 111b may be secured to each base 105a, 105b, respectively, through the use of threaded fasteners 112 (see, e.g., FIG. 2B). In some implementations, two or more clamps 111 may be secured to each base 105. In some implementations, the bottom side 107 of each base 105 may be configured to secure about a portion of a Weaver rail mount. In some implementations, the bases 105 may be configured to secure to any firearm mounting interface currently known or developed in the future.
In some implementations, a throw lever assembly (not shown but well known to those of ordinary skill in the art) may be used to secure the bases 105 to a firearm mounting interface (e.g., a Picatinny and/or Weaver rail mount) instead of the clamps 111 and fasteners 112 described above.
As shown in FIG. 1B, in some implementations, the first base 105a and the second base 105b each have a top side 109a, 109b (collectively top sides 109), respectively. In some implementations, each top side 109a, 109b defines thereon a first cutout 113a, 113b (collectively first cutouts 113), and a second cutout 114a, 114b (collectively second cutouts 114), respectively. In some implementations, the first cutout 113 and second cutout 114 of each base 105 is generally square (see, e.g., FIG. 1B). In some implementations, the first cutout 113 and second cutout 114 of each base 105 may be configured to receive therein lugs (not shown) located on the underside 118b of the bridge 115 (see, e.g., FIG. 2A-2B). In this way, a protruding member 106 located between the first cutout 113a, 113b and the second cutout 114a, 114b of each base 105a, 105b may resist the forward and/or rearward longitudinal movement of the bridge 115 (see, e.g., FIG. 1B).
As shown in FIGS. 1A and 1B, in some implementations, each base 105a, 105b may be removably secured to the underside of the bridge 115 through the use of threaded fasteners 116. In some implementations, each base 105a, 105b may be removably secured to the underside of the bridge 115 by any method known to one of ordinary skill in the art having the benefit of the present disclosure.
As shown in FIG. 1A, in some implementations, the first base 105a may include an offset mounting surface 145 extending therefrom. In some implementations, the offset mounting surface 145 may be configured to receive thereon a removable adaptor plate 150 (see, e.g., FIG. 2A). In this way, a user may select an adaptor plate 150 configured to receive thereon a reflex sight of their choice. In some implementations, the adaptor plate 150 may be secured to the offset mounting surface 145 through the use of threaded fasteners 152 (see, e.g., FIGS. 2A and 3B).
As shown in FIG. 2A, in some implementations, the offset mounting surface 145 may extend from a side of the first base 105a at an angle relative to the longitudinal axis of the modular scope mount assembly 100. In some implementations, the offset mounting surface 145 may extend from a side of the base 105a at an angle such that a top side of the adaptor plate 150, when secured thereto, is 35 degrees offset from the firearm mounting interface 205 to which the modular scope mount assembly 100 is secured (see, e.g., FIG. 5). In some implementations, offset mounting surface 145 may position the top side of the adaptor plate 150 to be more than 35 degrees offset (e.g., 45 degrees) or less than 35 degrees offset (e.g., 15 degrees), from the firearm mounting interface 205.
In some implementations, the adaptor plate 150 may have the general shape of a rectangle (see, e.g., FIG. 1A). In some implementations, the adaptor plate 150 may be any shape suitable for mounting a reflex sight thereon. In some implementations, the reflex sight may have an aiming point illuminated by electricity, tritium, a light emitting chemical reaction, or a combination thereof. In some implementations, the reflex sight may be an Aimpoint Micro® optical sight, a DOCTOR® red dot sight, a Leupold® Deltapoint, a Trijicon RMR®, or other sights having a similar foot print that are currently known or developed in the future.
As shown in FIG. 2A, in some implementations, the top side (or mounting surface) of the adaptor plate 150 may include a recoil lug 159 thereon. In this way, an attached reflex sight may be prevented from sliding back and forth due to the incidental vibrations associated with the discharge of a firearm.
As shown in FIGS. 1A and 3B, in some implementations, the bridge 115 may be a longitudinally extending member comprising a top side 118a and an underside 118b. In some implementations, the top side 118a of the bridge 115 may have a first mounting location 120a and a second mounting location 120b thereon (collectively mounting locations 120). In some implementations, the bridge 115 may be vertically canted (e.g., by 20 to 30 MOA) along its length. In some implementations, the top side 118a of the bridge 115 may taper along its length and be at an angle relative to its underside 118b. In this way, relative to the mounting interface (e.g., a Pica tinny rail 205) to which the modular scope mount assembly 100 is secured, the elevation of the first mounting location 120a may be different (e.g., higher) than the elevation of the second mounting location 120b. The bridge 115 being vertically canted may increase the usable elevation (or vertical) adjustment range of a telescopic sight mounted to the modular scope mount assembly 100. In some implementations, the top side 118a of the bridge 115 may not taper along its length (i.e., the top side 118a and the underside 118b of the bridge occupy parallel planes). In this way, relative to the mounting interface (e.g., a Picatinny rail) to which the modular scope mount assembly 100 is secured, the elevation of the first mounting location 120a may be the same as the elevation of the second mounting location 120b. In some implementations, the bridge 115 may include more than two mounting locations 120 thereon.
As shown in FIG. 2A, in some implementations, the first mounting location 120a and the second mounting location 120b of the bridge 115 may be configured to receive the lower ring portion 129a, 129b (discussed in detail below) of the first scope ring 125a and the second scope ring 125b, respectively, therein. In some implementations, the first mounting location 120a and the second mounting location 120b of the bridge 115 may each include a first side wall 122a, 122b and a second side wall 123a, 123b defining a recessed opening 124a, 124b, respectively, therebetween (see, e.g., FIG. 1A). In some implementations, each of the openings 124a, 124b may be configured to receive therein a portion of either the first lower ring portion 129a or the second lower ring portion 129b. In this way, the first side wall 122a, 122b and/or the second side wall 123a, 123b may resist the forward and/or rearward longitudinal movements of the scope rings 125.
As shown in FIGS. 1A and 1B, in some implementations, the first scope ring 125a and the second scope ring 125b may each comprise a lower ring portion 129a, 129b and an upper ring portion 131a, 131b, respectively. In some implementations, the lower ring portion 129a, 129b and upper ring portion 131a, 131b may be secured together through the use of threaded fasteners 133 (see, e.g., FIG. 2B). In some implementations, the upper ring portion 131a, 131b may be positioned and secured to the top side of the lower ring portion 129a, 129b, respectively, so as to form a complete ring surrounding a portion of the tube 235 of the telescopic sight 230 (see, e.g., FIG. 4). The construction of a scope ring(s) suitable for being secured about a portion of the tube 235 of a telescopic sight 230 known to those of ordinary skill in the art.
As shown in FIGS. 1A and 2A, in some implementations, each lower ring portion 125a, 125b may be removably secured to the bridge 115 through the use of threaded fasteners 135. In some implementations, each lower ring portion 125a, 125b may be removably secured to the bridge 115 by any method known to one of ordinary skill in the art having the benefit of the present disclosure.
To assemble a modular scope mount assembly 100 constructed in accordance with the present disclosure, in some implementations, the first base 105a is oriented so that the offset mounting surface 145 is positioned towards the right side of the modular scope mount assembly 100 prior to being attached to the underside 118b of the bridge 115 (see, e.g., FIG. 2A). Then, the first base 105a is positioned so that the lugs (not shown) on the underside of the bridge 115 are received within the first cutout 113 and second cutout 114 of the first base 105a. Next, threaded fasteners 116 are inserted through openings in the first base 105a from a bottom side 107a thereof and threadedly secured to the underside 118b of the bridge 115. Then, the second base 105b is positioned so that the lugs (not shown) on the underside of the bridge 115 are received within the first cutout 113 and second cutout 114 of the second base 105b. Next, threaded fasteners 116 are inserted through openings in the second base 105a from a bottom side 107b thereof and threadedly secured to the underside 118b of the bridge 115. Then, the lower ring portion 129a, 129b of each scope ring 125a, 125b is positioned within the opening 124a, 124b of a mounting location 120a, 120b (see, e.g., FIG. 2A). Threaded fasteners 135 are then inserted through openings in the bridge 115 from the underside 118b thereof and threadedly secured to each lower ring portion 129a, 129b (see, e.g., FIG. 1B). A telescopic sight 230 is then positioned so that a portion of the tube 235 extends across and is supported by both lower ring portions 129a, 129b (see, e.g., FIG. 4). An upper ring portion 131a, 131b may then be oriented and placed over the top side of each lower ring portion 129a, 129b, respectively, so as to form a complete ring surrounding a portion of the tube 235 of the telescopic sight 230 (see, e.g., FIG. 4). Threaded fasteners 133 are then inserted through openings in the upper ring portion 131a, 131b from a top side thereof and threadedly secured to the lower ring portion 129a, 129b, respectively (see, e.g., FIG. 2B).
As shown in FIGS. 3A and 5, in some implementations, to secure the reflex sight 250 to the adaptor plate 150, the reflex sight 250 may be oriented so that the openings 155 of the adaptor plate 150 are aligned with threaded openings located on a bottom side of the reflex sight 250. Threaded fasteners 155 are then inserted through the openings 155 of the adaptor plate 150 from a bottom side thereof and threadedly secured to the reflex sight 250. In some implementations, the adaptor plate 150 may be configured so that the fasteners securing a reflex sight thereto are threadedly secured to the adaptor plate 150.
To remove the reflex sight 250 from the adaptor plate 150, the above steps are performed in reverse.
As shown in FIG. 2A, to secure the adaptor plate 150 to the offset mounting surface 145 of the first base 105a, in some implementations, the adaptor plate 150 may be oriented so that the threaded openings 157 of the adaptor plate 150 are aligned with opening 147 extending through the offset mounting surface 145 (see, e.g., FIG. 1A). Threaded fasteners 152 are then inserted through the openings 147 in the offset mounting surface 145 from a back side thereof and threadedly secured to the openings 157 of the adaptor plate 150 (see, e.g., FIG. 3B).
In some implementations, an additional first base 105a having an offset mounting surface 145 thereon may be used in place of a second base 105b (i.e., two first bases 105a are used to secure the modular scope mount assembly 100 to a firearm mounting interface). In this way, for example, one reflex sight may be mounted on each side of the modular scope mount assembly 100.
In some implementations, an additional second base 105b may be used in place of a first base 105a (i.e., two second bases 105b are used to secure the modular scope mount assembly 100 to a firearm mounting interface).
In some implementations, the position on the underside 118b of the bridge 115 to which the first base 105a and second base 105b are mounted may be switched by the user. In this way, a user may reposition the adaptor plate 150 and attached reflex sight (i.e. the user may increase or decrease the eye relief between the user and the reflex sight).
In some implementations, each base 105a, 105b may be individually oriented to position the associated clamp 111a, 111b on either the left side (see, e.g., FIG. 2B) or the right side (not shown) of the modular scope mount assembly 100.
In some implementations, the base 105 having an offset mounting surface 145 thereon may be positioned to extend from either the left side or right side (see, e.g., FIG. 2A) of the modular scope mount assembly 100. In this way, the user may position an adaptor plate 150 and attached reflex sight on either side of the modular scope mount assembly 100.
In some implementations, not shown, the lower ring portion 129 of each scope ring 125 may extend from and be an integral part of the bridge 115 of the modular scope mount assembly 100.
