A high-quality, precision machined black crush washer for AR-style rifles, which is a perfect replacement or upgrade for existing parts to ensure correct alignment of flash suppressors, moderators or muzzle brakes.

These crush washers have been re-engineered for a better-looking assembly and improved fit, and will look great on any firearm.

The major diameter of these washers is 11/16 or .688. The standard diameter of a barrel is .7 at the muzzle. These will fit on any 1/2 thread, no matter the TPI. They ensure the proper torque because they crush at the correct specifications, then they act like a lock washer to keep end-of-barrel accessories such as muzzle brakes from loosening.
