The Wheeler AR-15 Receiver Lapping Tool squares the upper-receiver face so the barrel extension can mate against a truer surface. Used with a battery-powered or electric drill, the steel lapping tool helps improve barrel alignment, barrel-nut torque consistency, gas-tube alignment, and front-to-rear sight alignment.
