The Forster Universal Sight Mounting Fixture is a precision tool designed for drilling and tapping holes for scope mounts, receiver sights, and shotgun beads on various guns, including bolt action, lever action, and pump action firearms.
This jig ensures accurate hole spacing and alignment with its adjustable over-arm and interchangeable bushings, preventing drill "run out" and tap breakage, which are common issues in mounting sights.
Constructed from cast aluminum with hardened steel "V" blocks, the fixture is approximately 20 inches long and comes with a Drill and Tap Bushing Set for 6-48, with additional bushings available for purchase.
