FIELD OF THE DISCLOSURE
The present application relates to shooting rest attachments for firearms and more particularly to magazine floorplate monopod attachments for firearms.
BACKGROUND OF THE DISCLOSURE
It is an advantage to use a stabilizing support when shooting, particularly if the target is far away. Movement while aiming can cause significant shifts in the point of impact downrange, so it is desirable to stabilize the firearm as much as possible when shooting. Conventional shooting rests for firearms in the form of bipods or monopods are known in the prior art. For example, U.S. Pat. No. 7,669,357 to Moody et al, U.S. Pat. No. 7,478,496 to Bender, U.S. Pat. No. 7,197,844 to Benson, U.S. Pat. No. 7,124,528 to Long, U.S. Pat. No. 5,377,437 to Underwood and U.S. Pat. No. 4,393,614 to Pickett are all illustrative of the prior art.
While these inventions accomplish the task of stabilizing a firearm for improved accuracy, these devices add a significant amount of additional weight and bulk in order to provide the desired function. Likewise, said devices require some form of manipulation by the user prior to being used. Furthermore, due to the complexity of parts or materials used, the cost of manufacturing can be quite high. Accordingly, there exists a need in the art for a low cost and reliable shooting rest.
SUMMARY OF THE DISCLOSURE
Some or all of the above needs and/or problems may be addressed by certain embodiments of the present application. According to one example embodiment, the shooting rest may include a magazine floor coupling configured to couple to a bottom portion of a firearm magazine. The shooting rest may also include a lower extension extending downward from the magazine floor coupling. The lower extension may include a forward extension extending downward from a forward portion of the magazine floor coupling and a rearward extension extending downward from a reward portion of the magazine floor coupling. The forward extension may have a length greater than the rearward extension. Other example embodiments are discussed herein.
The shooting rest may provide a stable monopod shooting rest device at the base of a magazine fed firearm. The shooting rest improves upon the prior art by being significantly smaller, lighter, and cheaper to manufacture. Also, the shooting rest is always in the deployed position and requires no additional manipulation prior to use.
It is understood that the monopod shooting rest is not limited in its application to the details of construction and the arrangements of the components set forth in the following description or illustrations. The monopod shooting rest is capable of other embodiments and being produced in various alternative ways. Other embodiments, aspects, and features of the monopod shooting rest will become apparent to those skilled in the art from the following detailed description, the accompanying drawings, and the appended claims.

DETAILED DESCRIPTION OF THE DISCLOSURE
Illustrative embodiments will now be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all embodiments are shown. The present application may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Like numbers refer to like elements throughout.
According to an embodiment, an aspect of the present application is to provide a stable monopod shooting rest device at the base of a magazine fed firearm. The monopod shooting rest improves upon the prior art by being significantly smaller, lighter, and cheaper to manufacture. Also, the monopod shooting rest is always in the deployed position and requires no additional manipulation prior to use.
In certain aspects, the monopod shooting rest may be coupled to the magazine body without modify the existing attachment point in the magazine. For example, FIGS. 4-11C all illustrate various embodiments of a support structure for the firearm, in the form of a monopod shooting rest, which may replace the floorplate section of the magazine. In other aspects, the monopod shooting rest may be composed, at least in part, of one or more materials such as, but not limited to, reinforced nylon, ABS plastic, santoprene, synthetic santoprene, silicone, rubber, or the like, a combination thereof, or any suitable material for providing grip or traction when in use. The monopod shooting rest can be molded, overmolded, cast, or machined as an integral part of the floorplate replacement section, or it can be manufactured as a separate component and attached to the magazine, such as by fasteners or industrial adhesive.
The generic box fed magazine is a device that has been widely used to feed ammunition into firearms. The basic structure of the M16/AR box magazine 10, for example, is depicted in FIG. 1. The outer case of the magazine 21 is shaped to hold ammunition in a vertically stacked arrangement. The magazine includes a feed side 11, which dispenses ammunition into the feed mechanism of the firearm, and an end or floor side, which is covered by the floorplate 23. FIG. 2 is an exploded view of the box magazine referenced in FIG. 1 and depicts a magazine spring 24 and a magazine spring guide 22 that seats into a cutout 31 on the floorplate 23. Example box magazines may include the MagPul PMAG and/or the USGI 30-rd. One of ordinary skill in the art, however, will appreciate that the shooting rest discussed herein may be attached to the bottom portion of any box magazine known in the art by any means.
As shown in FIGS. 3A and 3B, an embodiment of a monopod shooting rest 100 may incorporate the replacement coupling for the magazine floorplate 23 in FIG. 1 as an integral part of its structure. Alternatively, the base of the structure may be fastened, such as by screws, adhesive or other suitable means, to an existing baseplate. The shooting rest 100 shown in FIG. 3A may be configured to be attached to the base of the box magazine in place of the standard floorplate with no additional modifications. FIG. 3A shows the replacement floorplate coupling 101 and a cutout 116 for seating the magazine spring guide. Other embodiments of the floorplate coupling 101 may not include the cutout 116; instead, the floorplate coupling 101 may include a similar configuration for attachment to the base of the box magazine as the floorplate it is intended to replace. The mounting method insures that the magazine spring and follower will function exactly the same as with the stock floorplate. Substantially adjacent to the floorplate coupling 101 is an extension 106, which forms a support section. The extension 106 may be comprised of differing suitable shapes, including extending a plurality of sides and molding them together. Due to the curvature of most box fed magazines, an element of the design is that a front portion 108 of the extension 106 be taller than a rear portion 110, so as to maintain the optimum muzzle pitch when the magazine is inserted into the firearm. The front portion 108 of extension 106 may be rolled to form small points 111 and 112, which serve to act as feet (contact points or surfaces) in anchoring the shooting rest into the ground. A lateral reinforcement bar 113 is provided between points 111 and 112 preferably with a slight arch to help create the spike effect which will aid with stability and prevent sliding along the ground. FIG. 3B is a frontal view of the shooting rest 100 which shows the pronounced arch formed by the lower lateral reinforcement bar 113 and also indicates an upper reinforcement bar 103 that is formed by creating a void between the upper and lower bars 113 and 103. The walls forming the cavity may be molded, cast, or machined and serve to lighten the device while providing greater structural support. A dimple 120 may be placed on either side of the forward edge to help provide a grabbing point for manipulating the shooting rest when the firearm is deployed, as illustrated in FIG. 4.
The rearward part of extension 106 may be tapered and also rolled to form small points 114 and 115 which will also create a spike like effect to aid stability. The edges of the points 111, 112, 114, and 115 may be radiused and/or rounded so as not to create sharp edges which could snag on other equipment or brush.
FIG. 5 shows an embodiment of the shooting rest 200 in accordance with an embodiment. In this embodiment, a magazine floor coupling 201 that is substantially identical to the standard floorplate is provided, as depicted in FIGS. 3A-3B. A forward extension 210 at a first end of the shooting rest 200 may include two equal sized protrusions 211 and 212 that extend downward to create the forward feet (contact points or surfaces) of the shooting rest 200. These protrusions may have slightly radiused and/or rounded corners along the leading edges 231 and 232 as well as the trailing edges 241 and 242 to prevent snagging on other equipment or objects. A rear extension 220 may include a spherical shape to allow for the shooting rest 200 to pivot along multiple axis, with two points of contact, if the shooter decides to cant or tilt the firearm. The rear extension 220 may be shorter in height relative to the front protrusions 211 and 212 to provide a desired muzzle pitch when the magazine is inserted into the firearm. The rear extension 220 may be serrated or have some other form of texturing to give it more traction on the surface.
FIGS. 6A and 6B depict a shooting rest 300 in accordance with an embodiment. In this embodiment, a magazine floor coupling 301 that is substantially identical to the standard floorplate is provided, as depicted in FIGS. 3A and 3B. In this embodiment, the lower extension 310 may comprise two equal length side runners 311 and 312 that run along the outer edge of the floor coupling 301, thereby creating the effect of dual feet to stabilize the firearm when the magazine is in use. The height of 311 and 312 may decrease progressively from a front end to a rear end in order to provide a desired muzzle pitch when the magazine is inserted into the firearm. The lower edges 326 of the runners 311 and 312 may be acute in a convex or concave configuration. Connecting the side runners 311 and 312 are two horizontal arrayed cross-members 303 and 313. The upper cross-member 303 and the lower cross-member 313 serve as structural reinforcements for the side runners 311 and 312. In between the cross-members 303 and 313 is a weight reduction cavity which can be formed by molding, casting or machining. The lower cross-member 313 may be arched upward along its lower edge 314 so the cross-member 313 does not come in contact with the ground when in use.
FIGS. 7 A and 7B depicts a shooting rest 400 in accordance with an embodiment. In this embodiment, a magazine floor coupling 401 that is substantially identical to the standard floorplate is provided, as in the embodiment of FIGS. 3A and 3B. As shown in FIG. 7A, the lower extension of shooting rest 400 may comprise a plurality of posts 412, 413, 414, and 415. In certain aspects, the front post 411 may be the largest and tallest, then four posts 412, 413, 414 and 415 may be arrayed in two parallel rows behind the front post 411 in descending height from front posts 412 and 413 to rear posts 414 and 415 to provide a desired muzzle pitch when the magazine is in use. FIG. 7B is a bottom view which shows the array of posts 412, 413, 414, and 415. In some instances, the bottom surface of each post 411, 412, 413, 414, 415 may be imprinted or cast with a knurled texture to provide better contact with the ground. While illustrated with a circular cross-section, the post may take other suitable shapes, such as triangular, oval, star, or the like, and may be of any desired height.
FIGS. 8A and 8B depict a shooting rest 500 in accordance with an embodiment. In this embodiment, a magazine floor coupling 501 that is substantially identical to the standard floorplate is provided as in the embodiment of FIGS. 3A and 3B. FIG. 8A is a perspective view of the shooting rest 500 having a plurality of rows of horizontally arrayed cross-members 511, 512, 513, and 514. The rows 511, 512, 513, and 514 may be in progressively descending height in order to provide a desired muzzle pitch when the magazine is in use. The distal ends of cross-members 511, 512, 513, and 514 may be arched upward to form a spike effect on the outer edge of each cross-members 511, 512, 513, and 514, providing better contact with the ground. The bottom surface of cross-members 511, 512, 513, and 514 may be knurled or serrated to provide more secure contact with the ground. While four rows are provided in shooting rest 500, any configuration with two or more rows may be suitable.
FIGS. 9A-9D depict a shooting rest 600 in accordance with an embodiment. In this embodiment, a magazine floor coupling 601 that is substantially identical to the standard floorplate is provided as in the embodiment of FIGS. 3A-3B. FIG. 9A is a perspective view of the shooting rest 600 having an upper extension 610 and a lower extension 612. The upper extension 610 may be molded to be wider, at least in part, than the lower extension 612 such that the appropriate structural strength is provided to the shooting rest 600. The upper section 610 may also include one or more index marks 614 and 616 on either side of the bottom exterior portion. Index marks 614 and 616 may be used for color coding or otherwise identifying the shooting rest 600, such as by a user or owner. Index marks 614 and 616, however, may be placed anywhere on the shooting rest 600. The lower extension 612 may comprise two equal length (and/or similarly shaped) side runners 618 and 620 that run along the outer edge of the floor coupling 601, thereby creating the effect of three or four feet (contact points or surfaces) to stabilize the firearm when the magazine is in use. The height of side runners 618 and 620 may decrease progressively from a front end to a rear end in order to provide a desired muzzle pitch when the magazine is inserted into the firearm.
The lower edges 622 may be acute in a convex or concave configuration. Additionally, the lower edges 622 may be formed in a shape similar to a lower case letter “r” or similar to a lower edge 326 of FIG. 6A but with a semi-ovular shape removed. Connecting the side runners 618 and 620 are two horizontal arrayed cross-members 624 and 626. The rear cross-member 624 and the front cross-member 626 may serve as structural reinforcements for the side runners 618 and 620. Additionally, the front cross-member 626 may be placed substantially horizontally to act as a contact with the ground when the firearm is being fired from a prone position. In some embodiments, the front cross-member 626 may be formed, at least in part, of a material such as, but not limited to, reinforced nylon, ABS plastic, santoprene, synthetic santoprene, silicone, rubber, a combination thereof, or the like, or any suitable material for providing grip or traction when in use. The bottom portions 628 of side runners 618 and 620 may also be made of any similar material, such as santoprene, or the like. Further, the bottom portions 628 and/or the bottom of the front cross-member 626 may be configured with a striped, cross-hatched, or other pattern or tread, or other type of textured material, for providing enhanced grip with a surface. Side runners 618 and 620 may also include a stipling pattern to enhance gripping the shooting rest 600. In some embodiments, overmolding may be employed to attach the upper extension 610 to the lower extension 612, the crossmembers 624 and 626 to the side runners 618 and 620, or any combinations thereof. Additionally, in some embodiments, protruding structural supports 629 may be provided to add enhanced structural support between the upper section 210 and the lower section 612.
FIG. 9B further details a concave cutout 630 for reducing weight of the shooting rest 600 and for providing a space for one or more fingers to be placed when a user grabs the shooting rest 600. Additionally, as seen in FIG. 9B, a front portion 632 of the lower extension 612 may be comprised of a heel shaped support that creates the effect of a front foot for stabilizing the firearm when the magazine is in use. In some embodiments, the front portion 632 may be molded individually and then overmolded with the rest of the lower extension 612. Further, in some embodiments, the entire lower extension 612 may be molded and then a santoprene or other suitable rubber or synthetic substance may be overmolded to the bottom of the lower extension 612 to create a slip-free surface on the contact points or surface(s).
As depicted in FIG. 9C, the front portion 632 of the lower extension 612 may be formed as a flat heel 634, thereby creating the effect of three feet (contact points or surfaces), in conjunction with the two rear ends of the side runners 618 and 620, to stabilize the firearm when the magazine is in use. Alternatively, as shown in FIG. 9D, the front portion 632 of the lower extension 612 may be formed as a concave heel 636 with two feet (contact points or surfaces), thereby creating the effect of four feet (contact points or surfaces), in conjunction with the two rear ends of the side runners 618 and 620, to stabilize the firearm when the magazine is in use.
FIGS. 10A and 10B depict a shooting rest 700 in accordance with an embodiment. In this embodiment, a magazine floor coupling 701 that is substantially identical to the standard floorplate is provided, as in the embodiment of FIGS. 3A-3B. The lower extension 710 may comprise a bladder 711. In some instances, the bladder 711 may be filled with jell, foam, sand, liquid, paste, loose particles, or other material that may be pliable within a bladder, for supporting, cushioning, and/or absorbing the weight of the firearm when the magazine is in use. Additionally, the bladder 711 may be attachable to an upper extension 712 of the floor coupling 701 by any known methods such as, but not limited to, adhesive fastening methods, protruding pin fastening methods, combinations of the foregoing or the like. The bladder 711 may be coated with any suitable material, such as, but not limited to, santoprene, synthetic santoprene, silicone, rubber, or any suitable material for providing grip to a surface. Further, the bladder 711 may be overmolded using any suitable materials, such as those listed above, to the upper extension 712. Alternatively, or in addition, the bladder 711 may be formed of solid santoprene or other anti-sliding material. In some embodiments, however, the bladder 711 may be formed of a solid material, hollowed out to form a cavity within the bladder, and then filled with pegs, jells, foam, sand, liquid, paste, loose particles, pressurized air or other gas, or other material for supporting, cushioning, and/or absorbing the firearm when the magazine is in use. Further, various levels of pliability and/or deformability may be achieved for the bladder 711 by varying the type of the filler, the density of the filler, the thickness of the bladder structure 711, the thickness of the outercoating, the size of the cavity, and/or whether spacers or dividers are used within the bladder to create channels within which filler material can reside.
FIGS. 11A-11C depict a shooting rest 800 in accordance with an embodiment. For example, a magazine floor coupling 801 that is substantially identical to the standard floorplate is provided, as in the embodiment of FIGS. 3A-3B. In this embodiment, the lower extension 810 is connected to the magazine coupling 801 by a singular side runner 820. The lower extension 810 may be molded and then a santoprene or other suitable rubber or synthetic substance may be overmolded to create a slip-free surface on the contact points to create one large contact point rather than multiple smaller contact points. The side runner 820 is tapered equally along its entire length to form a natural grabbing point for aiding in extraction of the magazine.
