J&E Machine Tech 7.62/.308 Crush Washer 5/8x24 Black Steel

The J&E Machine Tech 7.62/.308 Crush Washer is a precision-machined steel seating washer designed to correctly index and time flash hiders, muzzle brakes, and compensators on 5/8x24 threaded barrels. Manufactured in the USA with tight tolerances and a durable black finish, this washer is built to compress cleanly under torque so your muzzle device locks up precisely where you want it, with no shim stacks or guesswork required.

Engineered for AR-10 pattern rifles and any barrel cut with 5/8x24 threads, including common .308 Winchester and 7.62x51mm NATO chambers, this washer installs between the barrel shoulder and your muzzle device. Once torqued to spec, the crush washer permanently sets the orientation of the device, allowing ports, prongs, and timing features to align with the bore axis or your preferred sight picture.

Sold as 1 each, this is a simple, affordable must-have for any muzzle device installation on a large-bore rifle. Keep a spare on hand, because crush washers are a single-use component and must be replaced each time a muzzle device is removed and reinstalled.
