Description
The GrovTec Crush Washer is a precision muzzle device accessory engineered to properly seat and time compensators, muzzle brakes, and flash hiders on .308 caliber rifles. Designed for the popular 5/8″-24 thread pitch, this washer delivers consistent indexing and a secure fit under heavy recoil.
Manufactured from high quality steel with a premium black nitride finish, the GTHM320 provides excellent corrosion resistance and long service life in the field. Its controlled crush design allows proper timing of muzzle devices without binding or galling the threads, and the black nitride coating helps protect against wear from repeated installation and removal.
This package includes five crush washers, providing plenty of spares for multiple builds or replacements during re-installation. Whether you are mounting a new compensator or re-timing an existing setup, the GrovTec crush washer offers a reliable, repeatable solution for any .308 platform rifle with a 5/8″-24 threaded muzzle.
