Fixed stock assembly and method for forming the same

A fixed stock for Stoner-design rifles, the fixed stock comprising:

• a stock body with a receiver extension cavity formed therein, the receiver extension cavity extending from a receiver extension opening at the front end of the stock body towards the back end of the stock body;
• and
• at least one stock stabilizing member coupled to the stock body and movable between a first position and a second position, wherein when the at least one stock stabilizing member is in the first position, the stock stabilizing member does not prevent a carbine receiver extension from being inserted into and removed from the receiver extension cavity, and when the stock stabilizing member is in the second position, the stock stabilizing member prevents the carbine receiver extension from being inserted into and/or removed from the receiver extension cavity,
• wherein when a carbine receiver extension, having a front end and a back end, is positioned within the receiver extension cavity and the at least one stock stabilizing member is moved from the first position into the second position, the stock stabilizing member exerts a force onto the receiver extension and the stock body so that when the front end of the receiver extension is threaded into a lower receiver of a Stoner-design rifle, the front end of the stock body contacts the lower receiver, and the force exerted on the receiver extension is in a direction away from the lower receiver while the force exerted on the stock body is in a direction towards the lower receiver, causing the stock body to press against the lower receiver,
• wherein when the carbine receiver extension is positioned within the receiver extension cavity and the at least one stock stabilizing member is in the second position, all of the at least one stock stabilizing member is laterally positioned between the front end of the receiver extension and the back end of the receiver extension, and
• wherein the at least one stock stabilizing member is coupled to the stock body such that rotation of the at least one stock stabilizing member causes the magnitude of the force exerted on the carbine receiver to be adjusted.

• wherein when a carbine receiver extension, having a front end and a back end, is positioned within the receiver extension cavity and the at least one stock stabilizing member is moved from the first position into the second position, the stock stabilizing member exerts a force onto a surface of the receiver extension that is substantially perpendicular to a central axis of the receiver extension and the stock body so that when the front end of the receiver extension is threaded into a lower receiver of a Stoner-design rifle, the front end of the stock body contacts the lower receiver, and the force exerted on the receiver extension is in a direction away from the lower receiver while the force exerted on the stock body is in a direction towards the lower receiver, causing the stock body to press against the lower receiver,
