Stock for a firearm

Abstract

A release mechanism assembly for a stock of a firearm may comprise a first member, a first release mechanism, and a second release mechanism. The first release mechanism and the second release mechanism may be collectively configured to selectively prevent and allow the stock to move from a fully extended state to a partially extended state, and from the partially extended state to a fully collapsed state. The first release mechanism and the second release mechanism may be each configured to move with the first member while the stock moves between the fully extended state, the partially extended state, and the fully collapsed state.

         11 . The release mechanism assembly of  claim 1 , wherein the second release mechanism is configured to selectively prevent and allow a second member of the stock to move from an extended position to a collapsed position. 
     
     
         12 . The release mechanism assembly of  claim 11 , wherein the first member is configured to be at least partially nested within the second member in an instance in which the second member is in the collapsed position. 
     
     
         13 . The release mechanism assembly of  claim 11 , wherein:
 the first member comprises a cheek rest surface that extends circumferentially around a longitudinal axis at least 90 degrees, and   the second member comprises a cheek rest surface that extends circumferentially around the longitudinal axis at least 90 degrees.   
     
     
         14 . The release mechanism assembly of  claim 11 , wherein:
 the second release mechanism is configured to be in a first position and in a second position,   in an instance in which the second release mechanism is in the first position, the second release mechanism is configured to prevent a movement of the second member along a longitudinal axis relative to the first member, and   in an instance in which the second release mechanism is in the second position, the second release mechanism is configured to allow the movement of the second member along the longitudinal axis relative to the first member.   
     
     
         15 . The release mechanism assembly of  claim 11 , wherein:
 the first member is configured to be at least partially nested around a tube of the stock in an instance in which the first member is in the collapsed position,   the first member is configured to be slidingly engaged with a forward guide rod and an aft guide rod of the stock,   the forward guide rod is positioned exterior to the tube, and wherein the first member is configured such that in an instance in which the second member is in the extended position, and   the second member is positioned at least partially aft of the first member.   
     
     
         16 . The release mechanism assembly of  claim 11 , wherein:
 the first release mechanism is configured to selectively prevent and allow the first member of the stock to move from an extended position to a collapsed position, and   the first member is configured to be at least partially nested around a tube of the stock in an instance in which the first member is in the collapsed position.   
     
     
         17 . The release mechanism assembly of  claim 16 , wherein:
 the first member is configured such that in an instance in which the second member is in the extended position, the second member is positioned at least partially aft of the first member, and   the first member is configured to be nested within the second member in an instance in which the second member is in the collapsed position.
