Jam Nut for Muzzle Device, Round

Product Description

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.

• Colour varies but generally the Chunky style are gunmetal gray while the Slim style are darker, nearly black
• Use it to time a muzzle device if needed
• You don't need the crush washer if you are using this unless you're a belt-and-suspenders kinda guy
