The CVA Cascade Picatinny Scope Base (brand part no. DS611B) is a black one-piece rail built specifically for the CVA Cascade long action bolt gun, with 20 MOA of elevation built directly into the base for shooters stretching their rifle out to longer distances. It’s sized to accommodate scope tubes and objective bells up to 50mm without the front bell contacting the barrel, so a shooter isn’t forced into a compromise between magnification and mounting height. The Picatinny interface accepts standard 1913 rail rings, giving far more mounting flexibility than a proprietary two-piece base. It’s a direct, model-specific fit for the Cascade platform rather than a universal adapter.
