Abstract

A lower receiver for a modular firearm can include a first receiver portion that is removably attachable to a second receiver portion to form the lower receiver. An inner surface of the first receiver portion and an inner surface of the second receiver portion can together define a magazine cavity that is configured to receive a magazine. The lower receiver can be disassembled to provide easy access to inner regions of the lower receiver for cleaning, maintaining, or inspecting the modular firearm.

Claims

1. A lower receiver for a modular firearm, the lower receiver comprising:

a first receiver portion; and

a second receiver portion configured to mate with the first receiver portion along a mating surface, wherein an inner surface of the first receiver portion and an inner surface of the second receiver portion together define a magazine cavity configured to receive a magazine.

2. The lower receiver of claim 1, wherein the mating surface is located along a vertical plane that bisects the lower receiver from a front side surface to a rear side surface.

3. The lower receiver of claim 1, wherein the magazine cavity comprises a magazine opening along a bottom side surface of the lower receiver, and wherein the magazine opening is defined by a surface that slopes downward toward a front side surface of the lower receiver.

4. The lower receiver of claim 1, further comprising a plurality of finger recesses located on a front side surface of the lower receiver.

5. The lower receiver of claim 4, wherein the plurality of finger recesses comprises four finger recesses.

6. The lower receiver of claim 1, further comprising a plurality of finger recesses located on a side surface of the first receiver portion.

7. The lower receiver of claim 1, further comprising a plurality of finger recesses located on a side surface of the second receiver portion.

8. The lower receiver of claim 1, further comprising a first opening along a top side surface of the lower receiver and a first hole extending from a left side surface to a right side surface of the lower receiver, wherein the first opening is configured to receive a trigger assembly, and wherein the first hole is configured to receive a trigger pin to secure the trigger assembly within the first opening of the lower receiver.

9. The lower receiver of claim 1, further comprising an integrated trigger guard, wherein the first receiver portion comprises a first portion of the integrated trigger guard, and wherein the second receiver portion comprises a second portion of the integrated trigger guard.

10. A modular firearm comprising:

a lower receiver comprising;

a first receiver portion; and

a second receiver portion configured to mate with the first receiver portion along a mating surface, wherein an inner surface of the first receiver portion and an inner surface of the second receiver portion define a magazine cavity configured to receive a magazine.

11. The modular firearm of claim 10, wherein the mating surface is located along a vertical plane that bisects the lower receiver from a front side surface to a rear side surface.

12. The modular firearm of claim 10, wherein the magazine cavity comprises a magazine opening along a bottom side surface of the lower receiver, and wherein the magazine opening is defined by a surface that slopes downward toward a front side surface of the lower receiver.

13. The modular firearm of claim 10, further comprising a plurality of finger recesses located on a front side surface of the lower receiver.

14. The modular firearm of claim 10, wherein the plurality of finger recesses comprises four finger recesses.

15. The modular firearm of claim 10, further comprising a plurality of finger recesses located on a side surface of the first receiver portion.

16. The modular firearm of claim 10, further comprising a plurality of finger recesses located on a side surface of the second receiver portion.

17. The modular firearm of claim 10, further comprising a first opening along a top side surface of the lower receiver and a first hole extending from a left side surface to a right side surface of the lower receiver, wherein the first opening is configured to receive a trigger assembly, and wherein the first hole is configured to receive a trigger pin to secure the trigger assembly within the first opening of the lower receiver.

18. The modular firearm of claim 10, further comprising an integrated trigger guard, wherein the first receiver portion comprises a first portion of the integrated trigger guard, and wherein the second receiver portion comprises a second portion of the integrated trigger guard.

19. A left side portion of a lower receiver for a modular firearm, wherein the left side portion is configured to mate with a right side portion to form a lower receiver for a modular firearm.

20. (canceled)
