The Grovtec Crush Washer 308 Win 5 Pack is an essential component for armorers and shooters who need to properly index muzzle devices on large-frame rifles. These washers are critical for achieving the correct timing when installing muzzle brakes or flash hiders, ensuring both performance and safety during use.
Constructed from durable steel, these washers are designed to provide a secure lock-up without damaging barrel threads. The 5/8-24 thread pitch is the standard interface for .308 Winchester and 7.62 NATO platforms, making them compatible with a wide range of AR-10 and bolt-action rifles.
Whether you are a professional gunsmith or a dedicated enthusiast, these washers are ideal for fine-tuning compensators to effectively mitigate recoil during rapid fire. This five-pack ensures you have spares on hand for multiple projects or field repairs, making it a practical choice for those who frequently swap or upgrade muzzle accessories.
