The Weaver #414M Top-Mount Scope Base (Weaver part no. 48426) is machined specifically for the Remington 597 semi-auto rimfire rifle, giving this popular .22 platform a solid, factory-tight base for a scope. Weaver CNC-machines each base from aluminum to hold its geometry under recoil and finishes it in a black matte that matches the factory receiver. Because it’s cut to the exact screw pattern of the 597 receiver, there’s no drilling or gunsmithing involved — it bolts straight to the factory holes.
