(1) 5/8 Crush Washer

Crush Washers are designed to be “crushed” when tightened, creating the lock between the muzzle device and barrel shoulder. Something to note that is if you ever remove the muzzle device a new crush washer should be used to ensure the lock on reinstallation. For a muzzle device that doesn’t require alignment, a Crush Washer is superior.
