The EGW Ruger American Short Action Picatinny scope base with a 20 MOA incline (Evolution Gun Works part no. 46152) is a one-piece rail made for Ruger American short-action rifles. Evolution Gun Works machines it from domestic 6061-T6 extruded aluminum and finishes it in matte black anodizing. The 20 MOA slope gives a scope extra elevation travel for long-range work, and the Picatinny cross slots run the full length of the base so rings can sit wherever eye relief calls for. A channel down the center trims weight and often leaves the factory iron sights usable. Everything in the box, from the screws and wrench to the packaging, is made in the USA.

Key Specifications

• The rail is a one-piece Picatinny design, so a single base carries both scope rings.
• The incline is 20 MOA, which tilts the scope down to add elevation travel at long range.
• It is machined from domestic 6061-T6 extruded aluminum, a strong alloy that keeps weight low.
• The finish is matte black anodizing, which resists scratches and corrosion.
• Overall length is 6.67 inches, long enough to reach across the receiver and place rings freely.
• The center spread is 3.01 inches, which matches the hole spacing on the short-action receiver.
• Height is 0.4 inch from the top of the receiver to the top of the Picatinny rail, so the scope sits low.
• Weight is 2 ounces, a small addition to a hunting rifle.
• It fits Ruger American Standard, Predator, Compact, Ranch and Go Wild Camo models in short-action calibers.
• Mounting hardware is #6-48 x 1/4-inch screws and a T-10 bit, included with the base.
