The Weaver Grand Slam 2-Piece Steel Base for Mauser FN (Weaver part no. 48952) is machined to fit FN-pattern Mauser actions, a receiver footprint common on classic and custom bolt guns. Built from solid steel rather than lighter aluminum, it is designed to hold zero through heavy recoil and years of field use. The two-piece layout allows independent front and rear ring adjustment, and Weaver’s locking dovetail system keeps mounting rings seated securely every time a scope goes on or off. Finished in black, it gives an FN Mauser action a durable, no-nonsense scope foundation.
