Helpful Positive Review Worked great by Humble Johns Gunsmithing, Verified Owner, January 29, 2025

Product Info for Williams Gun Sight Scope Mount Drill Fixture

The Williams Scope Mount Drill Fixture is designed for drilling almost any receiver between the diameters of .630" to 1.535"; round, flat, or octagonal. With a hole spacing choice of .500", .605", or .860", you can install almost any scope mount base in the industry. The "scissors" action of the fixture will automatically center itself. The fixture comes complete with one each #31 and #28 hardened steel lock bushings for drilling #31 (6-48) and #28 (8-40) thread sizes. When locked into position, the lock bushings will not spin in the fixture, avoiding scratches around the drilled holes. After #31 holes are drilled, you can use the #28 bushing as a tap guide for 6-48 taps. You will have fewer broken taps and perfectly straight tapped holes. The Williams Scope Mount Drill Fixture is an excellent addition to any gunsmith's workbench.image
