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.
