Abstract

A muzzle device mounting system having a muzzle device having muzzle device locking lug recesses; a locking collar having locking collar locking lug recesses and being rotatable relative to the muzzle device between a locked position and an unlocked position; and a pin extending from the locking collar and into at least a portion of the pin channel to limit rotational movement of the locking collar relative to the muzzle device, wherein if the locking collar is in the unlocked position, the muzzle device locking lug recesses are aligned with the locking collar locking lug recesses and if the locking collar is in the locked position, the muzzle device locking lug recesses are not aligned with the locking collar locking lug recesses.

Claims (29)

1. A muzzle device mounting system, comprising:

a muzzle device having muzzle device locking lug recesses and having at least one ball detent recess formed in a portion of said muzzle device, wherein a tension element and a ball element are at least partially positioned within said at least one ball detent recess, and wherein a pin channel is formed within a portion of said muzzle device;

a locking collar having locking collar locking lug recesses and being rotatable relative to said muzzle device between a locked position and an unlocked position, wherein said locking collar includes a plurality of collar detents formed in a surface of said locking collar, wherein said collar detents are formed so as to interact with said at least one ball element; and

a pin extending from said locking collar and into at least a portion of said pin channel to limit rotational movement of said locking collar relative to said muzzle device, wherein if said locking collar is in said unlocked position, said muzzle device locking lug recesses are aligned with said locking collar locking lug recesses and if said locking collar is in said locked position, said muzzle device locking lug recesses are not aligned with said locking collar locking lug recesses.

2. The muzzle device mounting system of claim 1 , wherein said pin channel is an arcuate or partially arcuate pin recess or channel.

3. The muzzle device mounting system of claim 1 , wherein said collar detents provide tactile rotatable locking positions between said locked and unlocked positions.

4. The muzzle device mounting system of claim 1 , wherein a depth of at least some of said plurality of collar detents varies compared to a depth of at least some other of said plurality of collar detents.

5. The muzzle device mounting system of claim 1 , wherein larger or deeper collar detents are positioned relative to said locked and unlocked positions.

6. The muzzle device mounting system of claim 1 , further comprising a plurality of port apertures formed through a portion of said muzzle device.

7. The muzzle device mounting system of claim 1 , further comprising a plurality of port apertures extending radially from a muzzle device aperture of said muzzle device, toward the outer surface of said muzzle device.

8. A muzzle device mounting system, comprising:

a muzzle device having muzzle device locking lug recesses having a tension element and a ball element at least partially positioned within at least one ball detent recess, and having a pin channel formed within a portion of said muzzle device;

a locking collar having locking collar locking lug recesses and being rotatable relative to said muzzle device between a locked position and an unlocked position, said locking collar having a plurality of collar detents formed in a surface of said locking collar, having said collar detents formed so as to interact with said at least one ball element; and

a pin extending from said locking collar and extending into at least a portion of said pin channel to limit rotational movement of said locking collar relative to said muzzle device, such that if said locking collar is in said unlocked position, said muzzle device locking lug recesses are aligned with said locking collar locking lug recesses and if said locking collar is in said locked position, said muzzle device locking lug recesses are not aligned with said locking collar locking lug recesses.

9. The muzzle device mounting system of claim 8 , wherein said pin channel is an arcuate or partially arcuate pin recess or channel.

10. The muzzle device mounting system of claim 8 , wherein said collar detents provide tactile rotatable locking positions between said locked and unlocked positions.

11. The muzzle device mounting system of claim 8 , wherein said pin comprises a cylindrical pin, a cylindrical pin dowel, a roll pin, a tension pin, a split pin, or an expansion pin.

12. The muzzle device mounting system of claim 8 , wherein larger or deeper collar detents are positioned relative to said locked and unlocked positions.

13. The muzzle device mounting system of claim 8 , further comprising a plurality of port apertures formed through a portion of said muzzle device.

14. The muzzle device mounting system of claim 8 , further comprising a plurality of port apertures extending radially from a muzzle device aperture of said muzzle device, toward the outer surface of said muzzle device.

15. A muzzle device mounting system, comprising:

a muzzle device having muzzle device locking lug recesses having at least one ball detent recess, said at least one ball detent recess having a tension element and a ball element at least partially positioned therein, and having a pin channel formed within a portion of said muzzle device;

a pin extending from said locking collar and extending into at least a portion of said pin channel to bound rotational movement of said locking collar relative to said muzzle device, such that if said locking collar is in said unlocked position, said muzzle device locking lug recesses are aligned with said locking collar locking lug recesses.

16. The muzzle device mounting system of claim 15 , wherein if said locking collar is in said locked position, said muzzle device locking lug recesses are not aligned with said locking collar locking lug recesses.

17. The muzzle device mounting system of claim 15 , wherein said pin comprises a cylindrical pin, a cylindrical pin dowel, a roll pin, a tension pin, a split pin, or an expansion pin.

18. The muzzle device mounting system of claim 15 , wherein larger or deeper collar detents are positioned relative to said locked and unlocked positions.

19. The muzzle device mounting system of claim 15 , further comprising a plurality of port apertures formed through a portion of said muzzle device.

20. The muzzle device mounting system of claim 15 , wherein said pin channel is an arcuate or partially arcuate pin recess or channel.
