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.

This disclosure describes a firearm stock or arm brace with an adjustable length of pull. The stock or arm brace can include a body and lower stock, where the body includes a buffer tube receiving aperture and the lower stock includes a hollow cavity with a plunger and two concentric springs therein. One or more buttons can be affixed to sides of the plunger in the hollow cavity that can be used to depress the plunger against the force of one or both of the springs. One of the two springs may be shorter than the other and have a greater spring constant than the longer spring. Depressing the plunger against the taller spring may allow a user to adjust the length of pull while greater pressure and engagement of the second spring allows the stock or arm brace to be removed from a buffer tube or receiver extension.
