Use this lapping tool in a 3/8" electric drill to square the upper receiver face of an AR-15. This will improve the mating between the barrel and receiver & needs to be used with lapping compound. The pilot will also fit into the bolt carrier tunnel to keep perfect alignment throughout the receiver for improved accuracy.
