ATI Outdoors AR-15 Crush Washer 5-Pack – .223/5.56 Muzzle Device Installation

ATI Outdoors AR-15 crush washers provide reliable timing and gas seal for muzzle devices on .223/5.56 AR-15 barrels. These single-use washers compress during installation to create proper headspace between the barrel shoulder and muzzle device, allowing precise timing of flash hiders, compensators, and brakes without thread damage or excessive torque.

Each washer is designed for one-time use and should be replaced when reinstalling or timing muzzle devices. Carbon steel construction provides consistent compression. Compatible with standard 1/2x28 TPI muzzle threads common to AR-15 platform rifles. Five-pack ensures you have spares on hand for multiple installations or adjustments.
