TacFire Crush Washer Features The TacFire Crush Washer is a small but essential component for properly installing a muzzle brake compensator or flash hider onto an AR-15 or .223 caliber barrel. A crush washer deforms slightly under torque as the muzzle device is tightened down allowing the installer to achieve proper clocking and alignment without over-tightening the barrel threads. Stainless steel construction gives these washers the strength needed to compress correctly under torque while resisting the corrosion that can occur from repeated exposure to cleaning solvents and powder residue near the muzzle. Having a reliable supply of crush washers on hand makes any muzzle device swap or upgrade a straightforward process. Packaged 10 to a set this quantity gives shooters enough washers for several installations whether swapping muzzle devices between multiple rifles or simply keeping spares on hand for future upgrades. A finished silver stainless steel surface resists the fouling and residue that regularly collect near the muzzle of an AR-15 keeping these washers functional even after repeated use. Because crush washers are a single-use component once properly compressed having a stocked supply avoids delays when it comes time to change out a muzzle device. For anyone running an AR-15 platform this pack of crush washers is a practical low-cost addition to a parts bin.
