Luth-AR Crush Washer for AR-15 5.56 / .223 Rem 1/2x28 Steel

Luth-AR Crush Washer Features The Luth-AR Crush Washer is machined from steel and sized for 1/2x28 threaded barrels on the AR-15 platform in 5.56/.223 Rem giving it a proper fit against the barrel shoulder ahead of muzzle device installation. As the device is torqued down the washer compresses to fill any gap and take up rotational play allowing the device to land in the correct clocked position and stay there under recoil. This method is standard practice across AR-platform builds for properly indexing compensators flash hiders and brakes. At roughly 0.1 ounce the washer adds negligible weight while doing an outsized job holding the muzzle device secure. Because a crush washer deforms permanently once compressed it should be replaced any time a muzzle device is removed and reinstalled to maintain a reliable seal and proper clocking. Keeping several of these washers on hand saves a trip to the parts bin whenever a muzzle device needs to be swapped for cleaning testing a new brake or attaching a suppressor mount. This washer fits standard 1/2x28 threaded barrels on the AR-15 platform. It is a small essential part of any proper muzzle device installation.
