Abstract

Fixed stock assemblies and methods for forming fixed stock assemblies are provided. A fixed stock assembly includes a stock, or stock body, that has a receiver extension cavity extending therethrough and at least one stock stabilizing member. When a conventional carbine/collapsible receiver extension is positioned within the receiver extension cavity, the stock stabilizing member is actuated/adjusted/manipulated to extend into the receiver extension cavity and contact the receiver extension, thus exerting a force on receiver extension and/or a force on the stock. The stock stabilizing member may contact a surface of the receiver extension that is substantially perpendicular to a central axis of the receiver extension cavity and/or the receiver extension. The force on the receiver extension is in a direction away from the lower receiver, and the force on the stock is in a direction towards the lower receiver.

Claims

1. 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, and

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.

2. The fixed stock of claim 1, wherein the carbine receiver extension has a central axis, and where the force exerted on the carbine receiver extension is in a direction that is not parallel to the central axis of the carbine receiver extension.

3. The fixed stock of claim 2, wherein the at least one stock stabilizing member is coupled to the stock body such that the magnitude of the force exerted on the carbine receiver is adjustable.

4. The fixed stock of claim 3, wherein the when the at least one stock stabilizing member is in the second position, the at least one stock stabilizing member contacts a surface of the carbine receiver extension which is substantially perpendicular to the central axis of the carbine receiver extension.

5. The fixed stock of claim 4, wherein the surface of the carbine receiver extension which is substantially perpendicular to the central axis of the carbine receiver extension forms a side of a position detent on the carbine receiver extension.

6. The fixed stock of claim 5, 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 at least one stock stabilizing member to extend into the receiver extension cavity.

7. The fixed stock of claim 6, wherein an end of the at least one stock stabilizing member which contacts the surface of the carbine receiver extension is rounded or tapered.

8. The fixed stock of claim 6, wherein an end of the at least one stock stabilizing member which contacts the surface of the carbine receiver extension is made of nylon.

9. 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.

10. The fixed stock of claim 9, wherein the carbine receiver extension has a central axis, and where the force exerted on the carbine receiver extension is in a direction that is not parallel to the central axis of the carbine receiver extension.

11. The fixed stock of claim 9, wherein when the at least one stock stabilizing member is in the second position, the at least one stock stabilizing member contacts a surface of the carbine receiver extension which is substantially perpendicular to the central axis of the carbine receiver extension.

12. The fixed stock of claim 11, wherein the surface of the carbine receiver extension which is substantially perpendicular to the central axis of the carbine receiver extension forms a side of a position detent on the carbine receiver extension.

13. The fixed stock of claim 9, 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 at least one stock stabilizing member to extend into the receiver extension cavity.

14. The fixed stock of claim 13, wherein an end of the at least one stock stabilizing member which contacts the surface of the carbine receiver extension is rounded or tapered.

15. The fixed stock of claim 14, wherein an end of the at least one stock stabilizing member which contacts the surface of the carbine receiver extension is made of nylon.

16. 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 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,

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.
