Muzzle Device Timing and Alignment

The crush washer provides timing and alignment for muzzle devices during installation on threaded barrels chambered in .308 or 7.62 NATO. The washer compresses between the barrel shoulder and muzzle device during installation, allowing rotational adjustment to achieve proper orientation of ports, slots, or baffles. The compression creates a secure interface that maintains muzzle device position during use.

Single-Use Compression Design

The steel crush washer is designed for single-use application and compresses permanently during muzzle device installation. The compression deforms the washer material to create a tight fit between barrel shoulder and muzzle device. Once compressed, the washer should not be reused as the compressed material cannot return to original dimensions. A new crush washer should be used each time a muzzle device is removed and reinstalled.

Follow safe handling and manufacturer instructions. Use new crush washer for each muzzle device installation. Ensure compliance with all applicable federal, state, and local laws.
