The CMMG AR15 Crush Washer 1/2 is a precision-engineered component essential for proper AR-15 muzzle device installation and function. This crush washer is designed for shooters and gunsmiths who demand reliable barrel-to-muzzle-device alignment. It serves as a critical interface between your barrel threads and muzzle accessories, ensuring correct installation and preventing damage during removal cycles.
When properly torqued, the washer compresses and deforms plastically, locking the muzzle device in the correct angular position. This is particularly important for suppressors that require precise bore concentricity. The compact design and lightweight nature of the washer make it an indispensable addition to any AR-15 gunsmith kit or maintenance arsenal.
Law enforcement armorers, tactical operators, and civilian shooters building or maintaining AR-15 platforms benefit most from keeping spare crush washers on hand. The CMMG AR15 Crush Washer 1/2 is compatible with 1/2x28 threaded barrels, ensuring a secure fit for various muzzle devices including suppressors, flash hiders, and compensators.
