JE Machine Tech AR-15 Crush Washer 1/2x28 Steel Black

JE Machine Tech Crush Washer Features The JE Machine Tech Crush Washer is machined from steel to the 1/2x28 thread pitch used on most .223 and 5.56 chambered rifles. As the muzzle device is tightened the washer crushes and deforms to take up the remaining thread gap letting the installer rotate the brake or flash hider into a properly indexed square position. This is the standard method for mounting a muzzle device without needing to time the barrel threads or shim the gap with other hardware. A properly crushed washer also helps keep the device from loosening under the repeated recoil of live fire. Made in the USA this washer is sold as a single piece so builders can keep spares on hand for future installs or swaps between muzzle devices. It is a small inexpensive part but a correctly sized and properly crushed washer is essential to a clean professional looking muzzle device installation. Any AR-15 or similar platform using a 1/2x28 threaded barrel can use this washer when mounting a compensator brake or flash hider. Keeping a few of these on hand makes future muzzle device changes quick and straightforward.
