Universal Sight Mounting Fixture Instructions

The Forster Universal Sight Mounting Fixture was designed to meet the exacting requirements of gunsmiths who drill and tap holes for the mounting of scope mounts, receiver sights and shotgun beads. It helps guarantee that both spacing and alignment are straight and true. The fixture will accommodate any single barrel long gun including bolt actions, lever actions and pump actions as long as the barrel can be laid into the ”V” blocks of the fixture. Tubular magazine guns can be drilled in the same manner as other firearms by simply removing the magazine tube.

This fixturing tool will locate the holes to a standard spacing predetermined by the over-arm, which has standard built-in spacing increments of .500″ and .860″ between centers. Other non-standard spacing is also possible by sliding the over-arm in either direction. The over-arm is “keyed” and slides in a “T” slot. It’s always in true alignment with the exact center of the gun barrel.mount2

With our Universal Sight Mounting Fixture, drill “run out” is impossible because the drill is guided in a hardened and ground drill bushing. When you’re ready to tap the hole, another slip bushing of the correct size is substituted for the drill bushing to help guide the tap straight and true. This prevents breakage of taps due to cocking which is the major cause of damaged taps.

Our Universal Sight Mounting Fixture is a precision fixture that will justify its cost many times over and will allow you to do first-class work on your own or your customers’ firearms. The body is quality manufactured from an aluminum casting, then precision machined. The two “V” blocks are made from hardened steel accurately ground on the “V” as well as the shaft. The blocks are adjustable for height.
