Precision-machined aluminum jig is a fast, foolproof way to drill gas ports dead center on the top of the barrel and the correct distance from the gas block shoulder.

Each jig has a setscrew that keeps the barrel firmly in place. Tool steel drill bushing keeps the drill bit precisely aligned. Jig sets available for .750"" and .936"" OD barrels. Extra front jigs and drill bushings available separately. Complete instructions included. Mfg: Brownells SPECS: 6061 aluminum, and tool steel.
