Abstract

A magazine for storing cased telescoped (CT) cartridges and delivering the CT cartridges to a firearm configured to fire CT cartridges. The magazine includes a fixed lip and a moveable lip. The fixed lip and the moveable lip of the magazine are configured to prevent a CT cartridge located in a top-most position within the magazine from being pushed out a top of the magazine when the magazine is not fully inserted into a magazine well of the firearm configured to fire CT cartridges. The moveable lip may pivot laterally on a pivot point and move out of the way of the CT cartridge located in the top-most position within the magazine when the magazine is fully inserted and locked into the magazine well of the firearm configured to fire CT cartridges.

First claim

What is claimed is:

1. A magazine configured to store cased telescoped (CT) cartridges and deliver the CT cartridges to a firearm configured to fire CT cartridges, comprising:
a fixed lip;
a moveable lip; and
wherein the fixed lip and the moveable lip are configured to prevent a CT cartridge located in a top-most position within the magazine from being pushed out a top of the magazine until the magazine is fully inserted into a magazine well of the firearm configured to fire CT cartridges.

2. The magazine of claim 1 , wherein the fixed lip and the moveable lip are further configured to prevent the CT cartridge located in the top-most position within the magazine from being pushed out the top of the magazine while the magazine is being inserted into the magazine well of the firearm configured to fire CT cartridges.

3. The magazine of claim 2 , wherein the moveable lip is configured to move out of the way of the CT cartridge located in the top-most position within the magazine when the magazine is fully inserted and locked into the magazine well of the firearm configured to fire CT cartridges.

4. The magazine of claim 3 , wherein the moveable lip is further configured to pivot laterally on a pivot point and move out of the way of the CT cartridge located in the top-most position within the magazine when the magazine is fully inserted and locked into the magazine well of the firearm configured to fire CT cartridges.

5. The magazine of claim 4 , wherein the moveable lip is further configured to pivot laterally on the pivot point and out of the way of the CT cartridge located in the top-most position within the magazine when a magazine release mechanism pushes against a lower end of the moveable lip.

6. The magazine of claim 5 , wherein the moveable lip is further configured to pivot laterally on the pivot point and out of the way of the CT cartridge located in the top-most position within the magazine when the magazine release mechanism pushes against the lower end of the moveable lip through a hole in a side of the magazine when the magazine is fully inserted into the magazine well of the firearm configured to fire CT cartridges.

7. The magazine of claim 6 , wherein pivoting the moveable lip laterally on the pivot point and out of the way of the CT cartridge located in the top-most position within the magazine allows the CT cartridge located at the top-most position within the magazine to be fed vertically out of the top of the magazine into alignment with a chamber of the firearm configured to fire CT cartridges.

8. The magazine of claim 7 , wherein allowing the CT cartridge located at the top-most position within the magazine to be fed vertically out of the top of the magazine into alignment with the chamber of the firearm configured to fire CT cartridges allows the CT cartridge located at the top-most position within the magazine to be loaded into the chamber of the firearm configured to fire CT cartridges and fired.

9. The magazine of claim 8 , wherein the fixed lip does not move when the moveable lip is pivoted laterally on the pivot point and out of the way of the CT cartridge located in the top-most position within the magazine.

10. The magazine of claim 9 , wherein the CT cartridge located in the top-most position within the magazine is one of a plurality of CT cartridges that are loaded in the magazine; and
wherein the magazine further comprises a spring-loaded follower that pushes upward against the plurality of CT cartridges that are loaded in the magazine.
