The EGW Ruger 10-22 Picatinny Scope Base (brand part number 46102) mounts a Picatinny-pattern rail directly to a Ruger 10-22 receiver, built to a 20 MOA incline. Evolution Gun Works machines the base from 7075 T6 aircraft-grade aluminum and finishes it in matte black for a durable, corrosion-resistant mount, running 7.064 inches overall with a 3.805-inch center spread between the two middle mounting holes. The base ships with socket-head Torx screws and a wrench for installation. Note this base will not fit the 10-22 Takedown. It’s made in the USA to EGW’s standard tolerances.

Frequently Asked Questions

What rifle does this base fit? The Ruger 10-22, and no other action.

Are scope rings included? No, this is the base only; you’ll need a separate set of Picatinny-pattern rings.

What does 20 MOA mean for my setup? The 20 MOA incline builds in extra elevation adjustment for long-range shooting, beyond what the scope’s turret alone provides.
