The Grovtec Crush Washer .223 5 Pack is an essential component for shooters and armorers who need to properly time and secure muzzle devices on AR-15 platform rifles. This 5-pack is ideal for those building multiple rifles or keeping spare parts on hand for routine maintenance and muzzle device upgrades.
These crush washers are designed to provide the necessary tension required to lock a muzzle device into place, preventing it from backing off during use. The 1/2x28 thread pitch is specifically intended for .223 Remington and 5.56 NATO barrels, ensuring a precise fit for standard muzzle threads.
Whether you are performing a new build or replacing a used washer, these components offer the reliability needed for tactical or competitive shooting. Their compatibility with standard .223 caliber platforms ensures a secure and professional installation every time you hit the range.
