Brownells 75th Anniversary - A Shooting Heritage

Helps True The Upper Receiver For Precise Barrel Fit & Maximum Accuracy

Cold-rolled steel lapping tool chucks into a 3/8" hand drill to easily “square” the upper receiver face on your AR-15. Helps ensure precise mating of barrel and receiver for added accuracy. Coat face of receiver with aluminum-oxide lapping compound; extra long pilot slides into the bolt carrier tunnel to maintain perfect concentricity with the receiver.
