US12782082 - Shock absorbing stock with adjustable length of pull

A shock absorbing stock with adjustable length of pull is provided having a body with at least one cavity. A spring is received within the cavity. A butt pad is attached to a butt pad mount, and a pull rod is attached to the opposite side of the butt pad mount. A bushing with a central passage and a longitudinal passage is held in the cavity. The pull rod can be secured to the bushing with a pull rod lock. The length of pull is determined by which hole of the pull rod is used to secure the pull rod to the bushing. Firearm shock is absorbed as the butt pad is stopped by the user, causing the bushing, which is fixed to the pull rod, to compress the spring against the collar. The spring has the same spring rate regardless of the length of pull selected.
