Abstract

A firearm muzzle attachment mechanism includes a muzzle device; a tapering adapter having an outer tapering end configured to connect with the muzzle device; a hollow adapter having an internally threaded portion and configured to receive the muzzle device; a muzzle attachment having an inner tapering end configured to connect with the outer tapering end of the tapering adapter; and a means for providing tension being received in a receiving slot formed on the muzzle attachment.

Claims (48)

1. A firearm muzzle attachment mechanism, comprising:

a muzzle device;

a tapering adapter having an outer tapering end configured to contact the muzzle device;

a hollow adapter having an internally threaded portion and configured to receive the muzzle device;

a means for providing tension between the hollow adapter and the muzzle attachment; and

a muzzle attachment having an inner tapering end configured to be in contact with the outer tapering end of the tapering adapter.

2. The firearm muzzle attachment mechanism of claim 1 , wherein the outer tapering end of the tapering adapter comprises a threaded end and an inclined portion integrally and outwardly thickened from the threaded end and a gun barrel end of a firearm is threadedly engaged with the tapering adapter.

3. The firearm muzzle attachment mechanism of claim 2 , wherein the inclined portion of the tapering adapter is in contact with the inner tapering end of the muzzle attachment.

4. The firearm muzzle attachment mechanism of claim 1 , wherein the muzzle attachment further comprises a middle-threaded portion configured to threadedly receive within the hollow adapter.

5. The firearm muzzle attachment mechanism of claim 1 , wherein the muzzle attachment further comprises a flanged tapering wall where the inner tapering end is formed thereinside.

6. The firearm muzzle attachment mechanism of claim 5 , wherein the muzzle device can be received inside the flanged taper wall of the muzzle attachment.

7. The firearm muzzle attachment mechanism of claim 1 , wherein the muzzle attachment further comprises a middle-threaded portion and a flanged tapering wall integrally extended from the middle-threaded portion.

8. The firearm muzzle attachment mechanism of claim 1 , wherein the muzzle device comprises an internally threaded surface to threadedly engage with a gun barrel end of a firearm.

9. The firearm muzzle attachment mechanism of claim 1 , wherein the hollow adapter comprises a plurality of teeth arranged adjacent to the internally threaded portion.

10. The firearm muzzle attachment mechanism of claim 1 , wherein the muzzle attachment comprises a cylindrical tube portion integrally and outwardly thickened from a flanged taper wall of the muzzle attachment, wherein a receiving slot is formed between the cylindrical tube portion and the flanged taper wall.

11. The firearm muzzle attachment mechanism of claim 1 , wherein the muzzle attachment comprises a middle portion defined between a cylindrical tube portion and a middle-threaded portion.

12. The firearm muzzle attachment mechanism of claim 11 , wherein the middle portion is outwardly thickened from a middle-threaded portion of the muzzle attachment and is sufficient to be received inside the hollow adapter.

13. The firearm muzzle attachment mechanism of claim 1 , wherein the means for providing tension comprises a wire spring having a ring portion encircling the muzzle attachment.

14. The firearm muzzle attachment mechanism of claim 1 , wherein the means for providing tension comprises a leg transversely extended from a ring portion, wherein the leg is received within the receiving slot of the muzzle attachment.

15. The firearm muzzle attachment mechanism of claim 1 , wherein the receiving slot is transversally formed on a middle portion of the muzzle attachment.

16. The firearm muzzle attachment mechanism of claim 1 , wherein the muzzle attachment further comprises a flanged taper wall having a reduced diameter which is smaller than a diameter of a cylindrical tube portion of the muzzle attachment.

17. The firearm muzzle attachment mechanism of claim 1 , wherein the muzzle attachment further comprises an opening defining an opening edge, wherein the inner tapering end is formed along the opening edge.

18. The firearm muzzle attachment mechanism of claim 1 , wherein a leg of the means for providing tension is received inside a groove formed on a plurality of teeth located inside the hollow adapter.

19. The firearm muzzle attachment mechanism of claim 1 , wherein the outer tapering end comprises a threaded end sufficient to be received within the muzzle attachment.

20. A firearm muzzle attachment mechanism, comprising:

a muzzle device;

a hollow adapter having an internally threaded portion and configured to receive the muzzle device;

a muzzle attachment; and

a means for providing tension between the hollow adapter and the muzzle attachment.

21. The firearm muzzle attachment mechanism of claim 20 , further comprising a tapering adapter having an outer tapering end configured to contact the muzzle device.

22. The firearm muzzle attachment mechanism of claim 21 , wherein the muzzle attachment has an inner tapering end configured to be in contact with the outer tapering end of the tapering adapter.

23. The firearm muzzle attachment mechanism of claim 22 , wherein the outer tapering end of the tapering adapter comprises a threaded end and an inclined portion integrally and outwardly thickened from the threaded end and a gun barrel end of a firearm is threadedly engaged with the tapering adapter.

24. The firearm muzzle attachment mechanism of claim 20 , wherein the muzzle attachment further comprises a middle-threaded portion configured to threadedly receive within the hollow adapter.

25. The firearm muzzle attachment mechanism of claim 23 , wherein the inclined portion of the tapering adapter is in contact with the inner tapering end of the muzzle attachment.

26. The firearm muzzle attachment mechanism of claim 20 , wherein the muzzle attachment further comprises a flanged tapering wall where the inner tapering end is formed thereinside.

27. The firearm muzzle attachment mechanism of claim 20 , wherein the muzzle attachment further comprises a middle-threaded portion and a flanged tapering wall integrally extended from the middle-threaded portion.

28. The firearm muzzle attachment mechanism of claim 20 , wherein the muzzle device comprises an internally threaded surface to threadedly engage with a gun barrel end of a firearm.

29. The firearm muzzle attachment mechanism of claim 20 , wherein the hollow adapter comprises a plurality of teeth arranged adjacent to the internally threaded portion.

30. The firearm muzzle attachment mechanism of claim 20 , wherein the muzzle attachment comprises a cylindrical tube portion integrally and outwardly thickened from a flanged taper wall of the muzzle attachment, wherein the receiving slot is formed between the cylindrical tube portion and the flanged taper wall.

31. The firearm muzzle attachment mechanism of claim 20 , wherein the muzzle attachment comprises a middle portion defined between a cylindrical tube portion and a middle-threaded portion, and the receiving slot is formed on the middle portion.

32. The firearm muzzle attachment mechanism of claim 20 , wherein the means for providing tension comprises a wire spring having a ring portion encircling the muzzle attachment.

33. The firearm muzzle attachment mechanism of claim 20 , wherein the means for providing tension comprises a leg transversely extended from a ring portion, wherein the leg is received within the receiving slot of the muzzle attachment.

34. The firearm muzzle attachment mechanism of claim 20 , wherein the receiving slot is transversally formed on a middle portion of the muzzle attachment.

35. The firearm muzzle attachment mechanism of claim 20 , wherein the muzzle attachment further comprises a flanged taper wall having a reduced diameter which is smaller than a diameter of a cylindrical tube portion of the muzzle attachment.
