J&E Machine Tech 5.56/.223 Crush Washer Black 1/2x28

The J&E Machine Tech 5.56/.223 Crush Washer is a precision-machined steel shim built to correctly time and index your AR-15 muzzle brake, compensator, or flash hider. Crush washers deform under torque to take up the gap between the device's shoulder and the barrel step, letting the shooter set the orientation of the ports or baffles exactly where they want them on a standard 1/2x28 threaded 5.56 NATO / .223 Remington barrel. Finished in black and Made in USA, this single washer is a go-to install consumable for any builder or armorer working on the AR-15 platform.
