Abstract

A ratcheting magazine for a firearm includes a main body, a floor plate, and an insert disposed inside the main body. The insert includes a front column of supports, a rear column of supports, and a sliding column of supports. The sliding column of supports includes a plurality of positions relative to the insert such that the sliding column of supports moves linearly relative to the insert.

First claim

That which is claimed is:

1. A ratcheting magazine for a firearm comprising:
a main body;
a floor plate comprising an opening at a bottom of the ratcheting magazine; and
an insert disposed inside the main body, wherein:
the insert comprises a front column of supports, a rear column of supports, and a sliding column of supports;
the opening is sized such that at least one cartridge can be inserted into the ratcheting magazine through the opening; and
the sliding column of supports comprises a plurality of positions relative to the insert such that the sliding column of supports moves linearly relative to the insert.

2. The ratcheting magazine of claim 1 , wherein the insert is a separate component from the main body.

3. The ratcheting magazine of claim 1 , wherein the floor plate comprises a plurality of arms adjacent to the opening, wherein the plurality of arms guide cartridges into the ratcheting magazine.

4. The ratcheting magazine of claim 1 , wherein the floor plate comprises a plurality of arms adjacent to the opening, wherein the plurality of arms restrict movement of cartridges out of the ratcheting magazine.

5. The ratcheting magazine of claim 1 , wherein each of the supports of the front column of supports, the rear column of supports, and the sliding column of supports comprises a deployed position and a retracted position.

6. The ratcheting magazine of claim 1 , further comprising a rotating actuator that is mechanically linked to the linear movement of the sliding column.

7. The ratcheting magazine of claim 6 , wherein the rotating actuator comprises a hole for a mechanical connection between the rotating actuator and the sliding column.

8. The ratcheting magazine of claim 6 , wherein the rotating actuator comprises a protrusion extending upward from the ratcheting magazine.

9. The ratcheting magazine of claim 8 , wherein the protrusion of the rotating actuator is configured to interface with a bolt carrier group when the ratcheting magazine is inserted into the firearm.

10. The ratcheting magazine of claim 9 , wherein movement of the protrusion of the rotating actuator from a rear position to a front position cause the sliding column to move from a lowermost position to an uppermost position.

11. A ratcheting assembly for use with a firearm magazine body, the ratcheting assembly comprising:
a floor plate; and
an insert, wherein:
the insert comprises at least one static column of supports and a sliding column of supports; and
the sliding column of supports comprises a plurality of positions relative to the insert such that the sliding column of supports moves linearly relative to the insert, wherein:
the at least one static column of supports comprises a front column of supports and a rear column of supports; and
each of the supports of the front column of supports, the rear column of supports, and the sliding column of supports comprises a deployed position and a retracted position.

12. The ratcheting assembly of claim 11 , further comprising an opening adjacent to a bottom of the firearm magazine body, wherein the opening is sized such that at least one cartridge can be inserted into the firearm magazine body through the opening.

13. The ratcheting assembly of claim 12 , further comprising a plurality of arms adjacent to the opening, wherein the plurality of arms guide cartridges into the firearm magazine body.

14. The ratcheting assembly of claim 12 , further comprising a plurality of arms adjacent to the opening, wherein the plurality of arms restrict movement of cartridges out of the firearm magazine body.

15. The ratcheting assembly of claim 12 , wherein the opening extends through the floor plate.

16. The ratcheting assembly of claim 11 , further comprising a rotating actuator that is mechanically linked to the linear movement of the sliding column.

17. The ratcheting assembly of claim 16 , wherein the rotating actuator comprises a hole for a mechanical connection between the rotating actuator and the sliding column.

18. The ratcheting assembly of claim 16 , wherein the rotating actuator comprises a protrusion extending upward from the firearm magazine body.

19. The ratcheting assembly of claim 18 , wherein the protrusion of the rotating actuator is configured to interface with a bolt carrier group when the firearm magazine body is inserted into the firearm.

20. The ratcheting assembly of claim 19 , wherein movement of the protrusion of the rotating actuator from a rear position to a front position cause the sliding column to move from a lowermost position to an uppermost position.

21. A ratcheting magazine for a firearm comprising:
a main body;
a floor plate; and
an insert disposed inside the main body, wherein:
the insert comprises a front column of supports, a rear column of supports, and a sliding column of supports;
the sliding column of supports comprises a plurality of positions relative to the insert such that the sliding column of supports moves linearly relative to the insert; and
each of the supports of the front column of supports, the rear column of supports, and the sliding column of supports comprises a deployed position and a retracted position.

22. The ratcheting magazine of claim 21 , further comprising an opening adjacent to a bottom of the firearm magazine body, wherein the opening is sized such that at least one cartridge can be inserted into the firearm magazine body through the opening.

23. The ratcheting magazine of claim 22 , wherein the opening extends through the floor plate.

24. A ratcheting magazine for a firearm comprising:
a main body;
a floor plate;
an insert disposed inside the main body; and
a rotating actuator, wherein:
the insert comprises a front column of supports, a rear column of supports, and a sliding column of supports;
the sliding column of supports comprises a plurality of positions relative to the insert such that the sliding column of supports moves linearly relative to the insert; and
the rotating actuator is mechanically linked to the linear movement of the sliding column.

25. The ratcheting magazine of claim 24 , further comprising an opening adjacent to a bottom of the firearm magazine body, wherein the opening is sized such that at least one cartridge can be inserted into the firearm magazine body through the opening.

26. The ratcheting magazine of claim 25 , wherein the opening extends through the floor plate.
