The Luth-AR BL-06CW .223/5.56 Crush Washer 1/2x28 is a small but essential component designed to properly secure and time muzzle devices on AR-15 pattern rifles. Built from durable steel with a black finish, this factory replacement washer sits between the barrel shoulder and your flash hider, compensator, or muzzle brake to help achieve correct alignment.

This crush washer is sized specifically for .223 Remington and 5.56x45mm NATO barrels using standard 1/2x28 threads, making it a straightforward solution for new builds, barrel swaps, or replacing a worn original part. By deforming slightly under torque, it helps lock your muzzle device in place for consistent performance at the range or during training. Luth-AR’s attention to fit and function makes this a dependable choice for maintaining your rifle setup.
