US12332015 - Firearm stock with hydraulic dampening

The disclosure relates to the firearms and accessories manufacturing sector, and more specifically to a stock with a hydraulic damping system and anatomical regulation that supports and controls the shooter, allowing them to hold the weapon stably while aiming and firing accurately. This invention discloses a stock with a hydraulic damping system that aims to significantly reduce the impact of firing on firearms. The stock uses an internal hydraulic mechanism that absorbs and disperses some of the energy generated by the impact, providing a smoother and more comfortable shooting experience for the shooter. The hydraulic damping system consists of a piston, oil chamber and valve assembly designed to work together. When the gun is fired, the impact causes the piston to move inside the oil chamber, compressing the hydraulic fluid. This movement creates a controlled resistance, which helps cushion the impact and dissipate the energy of the gun shot.

The patent describes a firearm stock featuring a hydraulic damping system designed to enhance stability and reduce recoil impact during shooting. This innovative stock incorporates various components, including an adjustable aluminum base and a hydraulic mechanism, to provide a smoother shooting experience by absorbing and dispersing energy generated from gunfire.

Claim 1

A firearm stock with hydraulic damping comprising a wooden stock adjuster (N) that receives an aluminum base (N 1 ) through screws (N 2 ), and the base has screws for height adjustment (N 3 ) that are attached to a support (N 4 ), which has screws of different lengths (N 5 ); a wooden handle (E) and a rubber threshold(S) which is joined by screws (S 1 ) to an aluminum base (S 2 ) which is joined by screws (S 3 ) to an aluminum ball base (S 4 ) equipped with a clamping cradle (S 5 ), and characterized in that the handle (E) is integrated through a fixing screw (E 1 ) and a bushing (E 2 ) to a damper adjustment screw (A 1 ) which is incorporated into an aluminum chassis tube (A 2 ) which internally receives a length adjustment tube (A 3 ) which is integrated into the rubber threshold(S) through an adjustment ball (A 4 ) equipped with a length adjustment screw (A 5 ) which is attached to the aluminum ball base (S 4 ) and to the clamping cradle (S 5 ), and which internally receives an aluminum shock absorber sealing nut (A 6 ) that has a spiral spring (A 7 ) in contact with a piston (A 8 ) that has a flow control valve (A 9 ), surrounded by a fluid scraping ring (A 10 ) and a flow adjustment screw (A 11 ) being arranged in a sealing retainer (A 12 ) of an aluminum damper cylinder (A 13 ), which is connected to a damper support (A 14 ) through a set screw (A 15 ); the aluminum chassis tube (A 2 ) is fixed to the stock adjuster (N) through the screw (N 3 ), and the aluminum shock absorber sealing nut (A 6 ) also receives a screw (N 5 ) for fixing the stock adjuster; and a screw (A 16 ) and fixation latch (A 17 ) for fixing the length adjustment tube (A 3 ).
