Abstract

Semi-automatic rimfire rifles have a frame, a bolt operable to reciprocate within the frame, the bolt defining a bolt axis, the bolt defining a firing pin passage, a first firing pin portion received within at least a first portion of the firing pin passage, a second firing pin portion separate from the first firing pin portion received within at least a second portion of the firing pin passage, and the first firing pin portion being operable to contact the second firing pin portion such that the second firing pin portion discharges a cartridge in response to the first firing pin portion being struck by a hammer. The first firing pin portion may define a first firing pin axis aligned with the bolt axis. The second firing pin portion may have a nose portion that is offset from the bolt axis extending away from the first firing pin portion.

Claims

1. A firearm comprising:

a frame;

a bolt operable to reciprocate within the frame;

the bolt defining a bolt axis;

the bolt defining a firing pin passage;

a first firing pin portion received within at least a first portion of the firing pin passage;

a second firing pin portion separate from the first firing pin portion received within at least a second portion of the firing pin passage; and

the first firing pin portion being operable to contact the second firing pin portion such that the second firing pin portion discharges a cartridge in response to the first firing pin portion being struck by a hammer.

2. The firearm of claim 1 wherein the first firing pin portion defines a first firing pin axis aligned with the bolt axis.

3. The firearm of claim 2 wherein the second firing pin portion has a nose portion operable to strike a cartridge and extending away from the first firing pin portion, the nose portion being offset from the bolt axis.

4. The firearm of claim 1 wherein the firearm is chambered for a rimfire cartridge.

5. The firearm of claim 1 wherein the firearm is auto-loading.

6. The firearm of claim 1 wherein the bolt included a movable and removable extractor, and wherein the extractor in part defines the pin passage.

7. The firearm of claim 6 wherein the second firing pin portion is received between the extractor and a portion of the bolt.

8. The firearm of claim 1 wherein the first firing pin portion has a forward end, and wherein the second firing pin portion has a rear recess receiving the forward end of the first pin portion.

9. The firearm of claim 1 wherein the second pin portion is movable to reciprocate in a direction parallel to the bolt axis, and has a forward end laterally offset from the bolt axis.

10. The firearm of claim 9 wherein the bolt has a forward bolt face defining a pin aperture receiving the forward end of the second firing pin portion.

11. A firearm firing mechanism comprising:

a bolt defining a bolt axis;

the bolt defining a firing pin passage;

a first firing pin portion received within at least a first portion of the firing pin passage;

a second firing pin portion separate from the first firing pin portion received within at least a second portion of the firing pin passage; and

the first firing pin portion being operable to contact the second firing pin portion such that the second firing pin portion discharges a cartridge in response to the first firing pin portion being struck by a hammer.

12. The firearm of claim 11 wherein the first firing pin portion defines a first firing pin axis aligned with the bolt axis.

13. The firearm of claim 12 wherein the second firing pin portion has a nose portion operable to strike a cartridge and extending away from the first firing pin portion, the nose portion being offset from the bolt axis.

14. The firearm of claim 11 wherein the firearm is chambered for a rimfire cartridge.

15. The firearm of claim 11 wherein the firearm is auto-loading.

16. The firearm of claim 11 wherein the bolt included a movable and removable extractor, and wherein the extractor in part defines the pin passage.

17. The firearm of claim 16 wherein the second firing pin portion is received between the extractor and a portion of the bolt.

18. The firearm of claim 11 wherein the first firing pin portion has a forward end, and wherein the second firing pin portion has a rear recess receiving the forward end of the first pin portion.

19. The firearm of claim 11 wherein the second pin portion is movable to reciprocate in a direction parallel to the bolt axis, and has a forward end laterally offset from the bolt axis.

20. The firearm of claim 19 wherein the bolt has a forward bolt face defining a pin aperture receiving the forward end of the second firing pin portion.
