The Talley RMSc Base (brand part no. RMSC-1022) mounts a Shield RMSc-footprint reflex sight directly to the Ruger 10/22 receiver, giving plinking and small-game rifles a fast, both-eyes-open red dot setup. Talley machines the base to the 10/22’s factory drilling pattern so it seats flush and returns a repeatable zero without a separate rail adapter. It’s aimed at 10/22 owners who want a compact reflex sight rather than a full-size scope on a rifle built for fast, casual shooting. Because it’s a receiver-specific mount, it keeps the sight low and close to the bore line instead of stacking extra height with a universal rail.

Key Specifications

• Ruger 10/22 receiver compatibility, using the factory drilling pattern.
