Abstract
A stock and recoil system for a firearm includes a lower receiver, a bolt carrier, and a stock assembly. The bolt carrier is reciprocally movable along an axis within an upper receiver carried by the lower receiver and includes a tubular rearward end defining a cavity with a rearwardly directed opening. The stock assembly is coupled the lower receiver and includes a receiver extension coupled to the lower receiver and aligned on the axis. An action spring is carried within the receiver extension and extends therefrom into the tubular rearward end of the bolt carrier. The action spring is movable between a compressed configuration and an expanded configuration during the firing cycle of the firearm. A butt plate is adjustably coupled to the receiver extension and is movable between an extended position and a collapsed position.
