Abstract

Claims (24)

1. An ejector mechanism for a firearm comprising:

an ejector disposed at a forward face of a bolt,

wherein the ejector comprises a hole extending in a fore/aft direction through the ejector.

2. The ejector mechanism of claim 1 , wherein the hole is aligned with a firing pin such that at least a portion of the firing pin can pass at least partially through the ejector.

3. The ejector mechanism of claim 1 , wherein the hole comprises a counterbore on a rear side of the ejector.

4. The ejector mechanism of claim 1 , wherein the ejector comprises a rear protrusion that extends into a corresponding hole in the bolt.

5. The ejector mechanism of claim 4 , wherein the corresponding hole in the bolt is disposed at a location on the forward face distal from the firing pin.

6. The ejector mechanism of claim 4 , wherein the corresponding hole in the bolt is disposed at bottom of the forward face.

7. The ejector mechanism of claim 4 , further comprising a spring disposed within the corresponding hole in the bolt.

8. The ejector mechanism of claim 1 , wherein the ejector comprises a flat surface such that the flat surface is defined by an offset from an extractor cavity of the bolt.

9. The ejector mechanism of claim 1 , wherein the ejector comprises a forward interface comprising (i) a contact surface that protrudes forward and (ii) a secondary surface that is offset rearward from the contact surface.

10. The ejector mechanism of claim 1 , wherein the ejector comprises a retaining hole configured to interface with a retaining pin.

11. An ejector mechanism for a firearm comprising:

an ejector disposed adjacent to a bolt carrier group, wherein the bolt carrier group comprises a bolt,

wherein at least a portion of the ejector is disposed at a center of the bolt.

12. The ejector mechanism of claim 11 , wherein the ejector comprises a hole designed to provide clearance for a firing pin to pass at least partially through the ejector.

13. The ejector mechanism of claim 12 , wherein the hole comprises a counterbore on a rear side of the ejector.

14. The ejector mechanism of claim 11 , wherein the ejector comprises a rear protrusion that extends into a corresponding hole in the bolt.

15. The ejector mechanism of claim 14 , wherein the corresponding hole in the bolt is disposed at a location on the bolt distal from the firing pin.

16. The ejector mechanism of claim 14 , wherein the corresponding hole in the bolt is disposed at bottom of the bolt.

17. The ejector mechanism of claim 11 , wherein the ejector comprises a flat surface such that the flat surface is defined by an offset from an extractor cavity of the bolt.

18. The ejector mechanism of claim 11 , wherein the ejector comprises a symmetric shape with at least two flat surfaces such that a first flat surface is compatible with an extractor on a right side of the bolt and a second flat surface is compatible with an extractor on a left side of the bolt.

19. The ejector mechanism of claim 11 , wherein the ejector comprises a forward interface comprising (i) a contact surface that protrudes forward and (ii) a secondary surface that is offset rearward from the contact surface.

20. The ejector mechanism of claim 11 , wherein the ejector comprises a retaining hole configured to interface with a retaining pin.
