Mil-Spec AR-15 Crush Washer for 1/2" Threads

Brand new crush washers for use in timing muzzle devices.  Suitable for use on 1/2 x 28 TPI barrels. 

Crush washers are one time use items, and must be replaced whenever a new muzzle device is installed.  A lot more convenient than shims or peel washers, crush washers are used routinely with flash hiders and muzzle brakes.


NOT use with suppressors/silencers, or suppressor/silencer mounts.  Crush washers do not deform concentrically and can later result in baffle strikes.
