Jam Nut for Muzzle Device, Hex

In stock
From CA$6.11 Regular Price CA$11.07

These are useful for timing (positioning) muzzle devices if you want to be able to adjust the position without using crush washers. With a wrench or two you can adjust your muzzle device multiple times back and forth until you find the right position. So it's like having a reusable crush washer.
