Guntec USA AR-15 Crush Washer .223 Steel

Guntec Muzzle Device Crush Washer Features The Guntec USA Muzzle Device Crush Washer is machined for 1/2x28 threaded barrels the standard thread pitch found on most 5.56 and .223 AR15 M16 and M4 pattern rifles. Made from aluminum with a matte finish the washer is designed to crush slightly as the muzzle device is torqued down locking the device at the correct rotational position without requiring shims. That crush fit is what allows a flash hider or brake to index properly relative to the bore so the device points exactly where it was designed to point. Getting this step right matters for both appearance and function on a properly built upper. Because it is a wear item meant to deform under torque keeping a few of these washers on hand is good practice for anyone who regularly swaps muzzle devices between barrels. The matte black finish blends in visually with most muzzle devices and barrel finishes so it does not stand out once installed. Its compact size keeps it easy to store in a small parts bin alongside other build hardware. Any AR15 builder or armorer replacing or installing a new muzzle device will find this washer a quick affordable fix.
