The Foster Scope Mounting Jig fills the exacting requirements of the most particular gunsmith. Will handle virtually all bolt action, lever action and pump guns! You have only to spoil one good gun with a faulty job and you've spent the price of the jig. We have sold a great number of these to gunsmiths during the recent years. The universal comment when we meet scope jig buyers later is "I don't know how I ever did business without it. Would rather almost do without my right arm than lose it now!"

SPEC: Approx. 20" (50.8cm) long. Comes complete with Drill and Tap Bushing Set for 6-48. Other bushings sold below.
