The UT Arms Drill Jig Fixture allows the purchaser to complete the UT Arms 80% AR-15 Receiver quickly with tools found in any handyman's tools box. If a purchaser has a drill or a drill press this drill jig will help finish the receiver. The drill jig itself is made in an ISO 9001 certified machines shop on CNC machine tools that also make the 80% AR-15 lower receivers. The jig uses steel pins to properly align with the receiver. The steel pins mate with the front and read take down pins. An allen screw holds the two drill jig halves together when attached to the lower receiver. To help protect the receiver from scratches the drill jig is machines out of certified aircraft grade 7075-T6 aluminum. Finally, the drill jig has location holes for the fire control group as well as the trigger well.
