The EGW 0 MOA scope base (brand part number 42200) is built specifically for the Winchester Model 70 WSM, machined from 6061-T6 extruded aluminum and finished in matte black. It measures 6.670 inches overall with a 3.514-inch center spread between the two middle mounting holes, and it ships with hex head mounting screws and the wrench needed to install them. EGW recommends torquing the screws to 20 inch-pounds with a drop of blue Loctite for a secure, long-term mount. Once installed, the base accepts standard Mil-Std 1913 Picatinny rings, giving your Model 70 WSM a modern, zero-MOA mounting platform.
