TacFire AR-10 Crush Washers Features The TacFire crush washer is a simple but essential part of installing a muzzle brake flash hider or compensator correctly on an AR-10 pattern rifle. A crush washer deforms slightly as it is tightened allowing the muzzle device to be indexed and torqued to a specific orientation such as straight up and down while still achieving a proper secure fit against the barrel shoulder. Because a crush washer is a single-use component once it has been crushed down having a supply of ten on hand means a shooter can swap muzzle devices repeatedly without running out mid-project. Made from steel these washers hold up to the torque and heat generated during normal firing. Finished in black oxide the washers resist corrosion and blend in visually with most muzzle devices and barrel finishes on an AR-10 build. This pack of 10 gives armorers gunsmiths and home builders a practical bulk supply for shop use or for anyone who regularly tests different muzzle devices on their rifle. Made in the USA and backed by a manufacturer s limited warranty these washers are a low-cost consumable worth keeping on hand. For anyone working on an AR-10 muzzle device install the TacFire Crush Washers are for sale at GrabAGun.
