Abstract

A 5.56 mm class bolt for a firearm including a first ejector housing to receive, through a first ejector opening, a first ejector and a second ejector housing to receive, through a second ejector opening, a second ejector.

Claims (23)

1. A 5.56 mm class bolt for a firearm, comprising:

a first ejector housing configured to receive, through a first ejector opening, a first ejector,

a second ejector housing configured to receive, through a second ejector opening, a second ejector; and

a retaining pin housing extending along a first axis, wherein the retaining pin housing intersects the first elector housing and the second ejector housing.

2. The 5.56 mm class bolt of claim 1 , wherein the first ejector includes a first cutout, and the first ejector is retained in the first ejector housing.

3. The 5.56 mm class bolt of claim 2 , wherein the second ejector includes a second cutout, and the second ejector is retained in the second ejector housing.

4. The 5.56 mm class bolt of claim 3 , further including a single retaining pin disposed in the retaining pin housing to engage the first cutout and the second cutout to retain the first ejector in the first ejector housing and to retain the second ejector in the second ejector housing.

5. The 5.56 mm class bolt of claim 4 , wherein the retaining pin is disposed at least partially within the first cutout and at least partially within the second cutout.

6. The 5.56 mm class bolt of claim 4 , wherein the first cutout is disposed to face outwardly relative to the bolt and wherein the second cutout is disposed to face outwardly relative to the bolt.

7. The 5.56 mm class bolt of claim 4 , wherein the first cutout is aligned with the second cutout.

8. The 5.56 mm class bolt of claim 5 , wherein the first cutout includes a first retaining pin contact surface, the second cutout includes a second retaining pin contact surface, and wherein the first retaining pin contact surface is at least substantially parallel to the second retaining pin contact surface.

9. A bolt for a firearm extending along a first axis, comprising:

a first ejector passage having a first opening on a face of the bolt and extending along a second axis, wherein the first ejector passage is configured to retain a first biasing member and a first ejector received via the first opening;

a second ejector passage having a second opening on the face of the bolt and extending along a third axis that is parallel to the first axis and the second axis, wherein the second ejector passage is configured to retain a second biasing member and a second ejector received via the second opening;

a retaining pin passage extending along a fourth axis that is perpendicular to the first axis, second axis, and third axis, wherein the retaining pin passage communicates with the first ejector passage and the second ejector passage and is configured to receive a retaining pin that retains the first biasing member, the first ejector, the second biasing member and the second ejector.

10. The bolt of claim 9 , wherein the bolt is a 5.56 mm class bolt.

11. The bolt of claim 9 , further comprising:

the first ejector contained within the first ejector passage, wherein the first ejector includes a first cutout;

the second ejector contained within the second ejector passage, wherein the second ejector includes a second cutout;

the retaining pin contained within the retaining pin passage, wherein the retaining pin interacts with the first cutout and the second cutout thereby limiting movement of the first ejector within the first ejector passage and the second ejector within the second ejector passage;

the first biasing member contained within the first ejector housing and configured to bias the first ejector; and

the second biasing member contained within the second ejector passage and configured to bias the second ejector.

12. The bolt of claim 11 , wherein the first cutout is disposed to face outwardly relative to the bolt and wherein the second cutout is disposed to face outwardly relative to the bolt.
