This crush washer provides a secure, reliable method for properly timing and aligning 1/2″ muzzle devices on AR-15 barrels and other compatible platforms. Its tapered design ensures a tight, gas-sealed fit as it compresses during installation, helping maintain correct orientation of flash hiders, compensators, and muzzle brakes.

Durable construction allows it to withstand repeated firing and heat cycles, making it an essential component for any muzzle device installation, upgrade, or rebuild where proper indexing and long-term stability are critical.
