Abstract

A firearm receiver assembly includes a receiver body, a threaded mount at a rear portion of the receiver body, a magazine release assembly including a magazine release portion on at least one side of the receiver body, a bolt release assembly including a bolt release central portion and a bolt release portion on at least one side of the receiver body, and a safety selector assembly including a safety portion on at least one side of the receiver body. The bolt release central portion translates vertically within a cavity of the receiver body.

First claim

That which is claimed is:

1. A firearm receiver assembly comprising:
a receiver body;
a threaded mount at a rear portion of the receiver body;
a magazine release assembly comprising a magazine release portion on at least one side of the receiver body;
a bolt release assembly comprising a bolt release central portion, a first bolt release portion on a left side of the receiver body, and a second bolt release portion on a right side of the receiver body; and
a safety selector assembly comprising a safety portion on at least one side of the receiver body,
wherein the bolt release central portion translates in a single direction without rotating within a cavity of the receiver body.

2. The firearm receiver assembly of claim 1 , wherein the receiver body comprises a polymer material.

3. The firearm receiver assembly of claim 1 , wherein:
the threaded mount is a separate component from the receiver body;
the receiver body comprises a polymer material; and
the threaded mount comprises a metallic material.

4. The firearm receiver assembly of claim 1 , wherein:
the magazine release portion comprises a first magazine release portion on a left side of the receiver body and a second magazine release portion on a right side of the receiver body;
an operator interface portion of the first magazine release portion and an operator interface portion of the second magazine release portion are symmetric relative to one another;
the first magazine release portion comprises a pivoting lever; and
the second magazine release portion comprises a pivoting lever.

5. The firearm receiver assembly of claim 4 , wherein at least one selected from the group of the first magazine release portion and the second magazine release portion comprises a pin defining a rotational axis.

6. The firearm receiver assembly of claim 5 , wherein the pin comprises a set screw with threads.

7. The firearm receiver assembly of claim 1 , wherein the bolt release central portion is a separate component from the first bolt release portion and the second bolt release portion.

8. The firearm receiver assembly of claim 1 , wherein:
the first bolt release portion comprises a pivoting lever and at least one operator interface portion;
the second bolt release portion comprises a pivoting lever and at least one operator interface portion; and
the at least one operator interface portion of the first bolt release portion and the at least one operator interface portion of the second bolt release portion are symmetric relative to one another.

9. The firearm receiver assembly of claim 1 , wherein:
the magazine release portion comprises a first magazine release portion on a left side of the receiver body and a second magazine release portion on a right side of the receiver body;
the bolt release portion comprises a first bolt release portion on a left side of the receiver body and a second bolt release portion on a right side of the receiver body; and
the safety portion comprises a first safety portion on a left side of the receiver body and a second safety portion on a right side of the receiver body.

10. A receiver assembly for a firearm comprising:
a receiver body comprising a left side and a right side;
a threaded mount at a rear portion of the receiver body;
a magazine release assembly comprising a first magazine release portion on the left side of the receiver body and a second magazine release portion on the right side of the receiver body; and
a bolt release assembly comprising a bolt release portion on at least one side of the receiver body, wherein:
the first magazine release portion comprising a pivoting lever that rotates about a first pin;
the second magazine release portion comprising a pivoting lever that rotates about a second pin; and
the first magazine release portion and the second magazine release portion contact one another approximately halfway between the first pin and the second pin.

11. The receiver assembly of claim 10 , wherein the receiver body comprises a polymer material.

12. The receiver assembly of claim 10 , wherein:
the threaded mount is a separate component from the receiver body;
the receiver body comprises a polymer material; and
the threaded mount comprises a metallic material.

13. The receiver assembly of claim 12 , wherein the threaded mount comprises a plurality of retaining features that engage a material of the receiver body.

14. The receiver assembly of claim 10 , wherein:
the bolt release assembly comprises a bolt release central portion; and
the bolt release central portion translates vertically within a cavity of the receiver body.

15. The receiver assembly of claim 10 , wherein an operator interface portion of the first magazine release portion and an operator interface portion of the second magazine release portion are symmetric relative to one another.

16. The receiver assembly of claim 10 , wherein the bolt release portion comprises a first bolt release portion on a left side of the receiver body and a second bolt release portion on a right side of the receiver body.

17. The receiver assembly of claim 16 , wherein:
the first bolt release portion comprises at least one operator interface portion; and
the second bolt release portion comprises at least one operator interface portion.

18. The receiver assembly of claim 17 , wherein the at least one operator interface portion of the first bolt release portion and the at least one operator interface portion of the second bolt release portion are symmetric relative to one another.

19. The receiver assembly of claim 10 , wherein at least one selected from the group of the first magazine release portion and the second magazine release portion comprises a recess on an interior side.

20. The receiver assembly of claim 10 , wherein at least one selected from the group of the first pin and the second pin comprises a set screw with threads.

21. The firearm receiver assembly of claim 1 , wherein the first bolt release portion interfaces with a forward side of the bolt release central portion and the second bolt release portion interfaces with a rear side of the bolt release central portion.

22. The firearm receiver assembly of claim 1 , wherein at least one selected from the group of the first bolt release portion, the second bolt release portion, and the magazine release portion comprise a removable external interfacing component that is separate from the internal mechanism for operation.
