Evolution Gun Works Winchester 70 Pre-64 STD/LA Picatinny Scope Base 20 MOA - Matte Black

The Evolution Gun Works Picatinny Scope Base is a one-piece Picatinny rail machined specifically for the Winchester Model 70 in Pre-64 Standard Action and Long Action configurations. Drilled to mate directly with the factory scope mount holes on the receiver, this rail provides a solid Picatinny mounting platform for any optic or ring setup, making it an ideal upgrade for these classic bolt-action rifles.

Built-in 20 MOA of elevation cant gives extra elevation adjustment for long-range shooting, allowing compatible optics to take full advantage of their internal elevation travel. The base is machined from 6061-T6 extruded aluminum and finished in a non-reflective matte black for a clean, low-glare appearance that blends with most factory and aftermarket barreled actions. A center spread of 3.805" ensures proper eye relief positioning for standard scope ring sets.

Installation is straightforward: the rail drops onto the factory receiver holes and is secured with the included socket head Torx screws and wrench, so no additional hardware is required. The Evolution Gun Works Winchester 70 Pre-64 STD/LA Picatinny rail is a simple, no-gunsmithing solution for adding a modern optic mounting interface to one of America's most beloved bolt-action platforms.
