The present invention relates generally to gadgets that may act as stabilizing attachments for firearms. More particularly, the present invention is related to an add-on attachment for improving the stability and usability of firearms.
Firearms such as pistols and revolvers are widely used around the world for self-defense, hunting, sports, and related activities. These handguns generate a considerable amount of recoil when fired. Recoil (often called knockback, kickback, or simply kick) is the backward movement of a gun when it is discharged. In technical terms, the recoil momentum acquired by the gun exactly balances the forward momentum of the projectile and exhaust gases, according to Newton's third law, known as conservation of momentum. In hand-held small arms, the recoil momentum is transferred to the ground through the body of the shooter.
Muzzle rise (also known as muzzle climb) is one of the most common physical phenomena in all widely used firearms. Muzzle rise more specifically refers to the elevation of the muzzle of the firearm, caused by combined recoil from multiple shots being fired in quick succession. It has an adverse effect on the accuracy of automatic and rapid-fire semi-automatic firearms, causing a target to be overshot.
The primary reason for muzzle rise is that for nearly all guns, the bore axis (longitudinal centerline of the barrel) is slightly above the gun's center of mass, while the contact points between the shooter and the gun (e.g. grips and stock) are often all below the center of mass. When the gun is fired, the bullet motion and the escaping propellant gases exert a reactional recoil directly backward along the bore axis, while the countering forward push from the shooter's hands and body are well below it. This creates a rotational torque around the center of mass, which causes the gun to pitch upwards and the muzzle end to rise.
It reduces the accuracy of firing and makes it challenging to engage a target efficiently. Users will have to take aims repeatedly due to the movement caused by such forces and makes it difficult to engage a target for a subsequent round. Besides, untrained shooters and shooters under stressful circumstances may try to provide opposing force in anticipation of the recoil causing the muzzle to go off target. As the power of the cartridge increases, recoil forces and muzzle rise increase proportionally.
The absence of components such as a shoulder stock causes all the recoil forces to be transferred to the shooter's hand and wrist. Since the firearm's recoil forces release suddenly when the firearm is fired, it is difficult for the muscles in the hand, wrist, and forearm to provide the necessary counterforce to counter the recoil forces and maintain stability. Handguns also typically have very short barrels. Hence, a small movement such as a short flinch, shake, or unsteadiness by the shooter will translate into a wide margin of error with respect to the target.
Among other solutions, adding more ergonomic contact points serves as a very effective solution to overcome the abovementioned problem. Add-on apparatuses such as firearm braces have proved to be highly effective in minimizing the adverse effects caused by recoil.
US20160265872A1 discloses accessories attached to firearm magazine. In a first aspect, a mounting system to mount accessories to the magazine or magazine baseplate of a firearm is provided. In a more specific best mode, a handgun forearm brace and recoil suppression support, for example, for target shooting, training, and improved aim is discussed. The support structure is connected via a locking mechanism to the base of the handgun detachable magazine and extending rearward to a rear connector. The forearm brace is further configured to allow it to adjust and extend either above and over the forearm of the shooter or below the forearm of the shooter. This improved support connecting to the base of the magazine via a locking mechanism can be used as a universal support for all guns with a detachable magazine without requiring any alternations, modifications, or attachments to the gun itself.

The apparatus disclosed herein is a firearm brace that may improve the overall efficiency of the firearm itself by improving its stability. The firearm brace disclosed herein may be a free-floating structure wherein the contact point that connects the pistol to the brace is at the rail under the barrel of the pistol. “Rail” herein refers to the entire family of firearm rails. Exemplary rails are Weaver rails and Picatinny rails, although other rails of various sizes and constructions known in the art or well within the grasp of the skilled artisan with routine design choices may be compatible with the disclosed apparatus as well.
Firearms such as pistols may be fastened onto the apparatus easily using standard commercially available fastening means such as Picatinny rails The Picatinny rail, or Pic rail for short, also known as a MIL-STD-1913 rail, is a military standard rail interface system that provides a mounting platform for firearm accessories. It was originally used for mounting scopes atop the receivers of larger caliber rifles. Once established, its use expanded to also attaching other accessories, such as iron sights, tactical lights, laser aiming modules, night vision devices, reflex sights, holographic sights, foregrips, bipods, slings and bayonets. Such interfaces are easily available in the market and are well known for their universal adaptability.
The rail consists of a strip undercut to form a “flattened T” with a hexagonal top cross-section, with cross slots interspersed with flats that allow accessories to be slid into place from the end of the rail and then locked in place. The Picatinny locking slot width is 0.206 in (5.23 mm). The spacing of slot centres is 0.394 in (10.01 mm) and the slot depth is 0.118 in (3.00 mm). Adding a Picatinny rail to the butt end of a revolver grip will allow for the attachment of all standard accessories. If the rail was oriented laterally with an appropriate locking means, it would give a stronger and more ergonomic connection means specifically for the purpose of attaching accessories such as cheek welds, forearm braces, monopods, and bipods to the firearm. The apparatus disclosed herein may be used along with pistols of various configurations and sizes by fastening it to the apparatus using standard Picatinny rails by means of fastening mechanisms such as Allen bolts.

In one example, a red dot sight may be fixed onto the top rail of the apparatus. Herein, red dot sight is a common classification for a type of non-magnifying reflector (or reflex) sight for firearms, and other devices that require aiming, that gives the user an Aimpoint in the form of an illuminated red dot. They are considered to be fast-acquisition and easy-to-use gun sights for target shooting, hunting, and in police and military applications. The connectors provided on the top side of the pistol brace allows attaching most of the commercially available standard red dot sights. The rear end support of the brace may be rested preferably near the shooter's cheek area or any other part of the user's body as understood by a person skilled in the art while firing shots using the firearms. The support brace 1008 may act as cheek weld or arm support while using the firearm. Users may adapt to different methods and techniques for positioning the rear end support according to their shooting style. The support brace 1008 may be rested at various contact points of the shooters body as understood by a person skilled in the art. Essentially, the brace reduces effects caused by recoil and helps the shooter stabilize their shot placement and assists the shooter in achieving more consistent short or medium range shots. The firearm brace disclosed herein improves the stability and usability of handguns.
The telescopic structure of the apparatus allows users to easily change the length of the brace as per their requirements. In one example, the extending rail of the apparatus may be configured with a spring-based functionality as well. Herein, the rail may be kept under a tension provided by a compression spring. Buttons/triggers may be used to push the rail outwards to instantly increase the length of the brace as and when required by the user.
