The Weaver Grand Slam 2-Piece Steel Base for CVA Round Receiver (Weaver part no. 48970) is machined specifically for CVA’s round-receiver muzzleloaders, giving these rifles a proper steel scope foundation instead of an improvised fit. Built from solid steel rather than lighter aluminum, it is designed to handle the heavy recoil common to muzzleloader cartridges without loosening or shifting zero. 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 is a straightforward upgrade for CVA owners who want a dependable optic mount.
