Strike Industries AR .308 Crush Washer Features The Strike Industries AR .308 Crush Washer is designed to compress during muzzle device installation allowing a brake or flash hider to be properly timed and aligned without loosening over time. Correct timing of a muzzle device matters both for its intended function whether reducing recoil or managing flash signature and for ensuring the device doesn t back off under recoil during firing. Using a quality crush washer rather than a worn or reused one helps achieve a tight secure fit the first time saving builders from having to remove and reinstall a muzzle device multiple times. Strike Industries has built its reputation in the AR parts market by focusing on components that solve practical building challenges like this one. Sold as a 10-pack this set of crush washers is well suited to shooters gunsmiths or builders working on multiple .308 pattern rifles who want a reliable supply on hand. Having spares available also means a builder won t be left searching for a replacement mid-project if a washer is damaged during installation. Finished in black these washers blend in visually with most muzzle device and barrel finishes common on .308 AR builds.
