Abstract

A fixed magazine for a rifle has a projecting boss within the magazine well that engages a cavity in the magazine. Once the magazine is inserted and the boss engages the cavity, the magazine is fixed and may not be removed from the rifle. The magazine is loaded by separating the upper receiver from the lower receiver and exposing the magazine opening, allowing it to receive rounds of ammunition.

First claim

What is claimed is:

1. In combination, a rifle and a magazine for ammunition, said rifle comprising:
a magazine well having an inwardly facing surface defining a space for receiving said magazine;
at least one boss projecting from said inwardly facing surface into said space, said at least one boss being immovable relative to said inwardly facing surface;
said magazine comprising:
a container having an opening for receiving said ammunition, said container having an outwardly facing surface, at least a portion of said container being positionable within said magazine well;
at least one cavity positioned in said outwardly facing surface of said portion of said container positionable within said magazine well, said at least one boss being engageable within said at least one cavity to prevent removal of said magazine from said magazine well.

2. The combination according to claim 1 , wherein said at least one cavity comprises a groove in said outwardly facing surface.

3. The combination according to claim 2 , wherein said groove is oriented substantially parallel to a firing axis of said rifle when said portion of said magazine is positioned within said magazine well.

4. The combination according to claim 1 , wherein said at least one cavity comprises:
a first surface oriented angularly with respect to said outwardly facing surface; and
a second surface, contiguous with said first surface, said second surface being oriented substantially perpendicular to said outwardly facing surface.

5. The combination according to claim 4 , wherein said second surface lies in a plane substantially parallel to a firing axis of said rifle when said portion of said magazine is positioned within said magazine well.

6. The combination according to claim 5 , wherein said second surface is positioned between said first surface and said opening of said container.

7. The combination according to claim 5 , wherein said first surface is positioned between said second surface and said opening of said container.

8. The combination according to claim 1 , further comprising a plurality of said cavities positioned in said outwardly facing surface.

9. The combination according to claim 8 , wherein at least two of said cavities are arranged on opposite sides of said container.

10. The combination according to claim 8 , wherein at least two of said cavities are arranged on the same side of said container.

11. The combination according to claim 1 , wherein said boss comprises:
a first surface oriented angularly with respect to said inwardly facing surface; and
a second surface, contiguous with said first surface, said second surface being oriented substantially perpendicular to said inwardly facing surface.

12. The combination according to claim 11 , wherein said second surface lies in a plane substantially parallel to a firing axis of said rifle.

13. The combination according to claim 12 , wherein said second surface is positioned between said first surface and said firing axis of said rifle.

14. The combination according to claim 12 , wherein said first surface is positioned between said second surface and said firing axis of said rifle.

15. The combination according to claim 1 , wherein said boss has a shape that is complementary to a shape of said cavity.

16. The combination according to claim 1 , further comprising a plurality of said bosses positioned on said inwardly facing surface of said magazine well.

17. The combination according to claim 16 , wherein at least two of said bosses are arranged on opposite sides of said magazine well.

18. The combination according to claim 16 , wherein at least two of said bosses are arranged on the same side of said magazine well.
