Mil-Spec AR-15 Peel Washer

Mil-Spec Peel Washers are made to fit 1/2x28 TPI threaded muzzles. At 0.73" thick, peel washers are useful for shimming and timing muzzle devices that also act as suppressor mounts.

Crush washers are not recommended for suppressor mounts, so it is best to use peel washers such as these, in combination with timing shims and a thread locking compound.
