Wheeler AR-10 Receiver Lapping Tool - 1082227

The Wheeler Tools AR-10 Upper Receiver Lapping Tool is designed to help create a square, true mating surface between the upper receiver and barrel extension for improved fit and accuracy potential. Constructed from durable steel with a black oxide finish, the lapping bar is built for repeated gunsmithing and rifle-building use. The tool is compatible with battery-powered or electric drills, making the lapping process faster and easier to complete. Properly lapping the receiver can also help improve barrel nut positioning, support ideal torque, and promote correct gas tube hole alignment during assembly. The kit includes a flex driver shaft, 220-grit lapping compound, and steel lapping bar, providing the essential components needed to lap a compatible AR-10 upper receiver.
