Hi-Lux Optics Winchester 1892/1894 Steel Red Dot Mount RMR Footprint Matte Black Small. Redesigned for a perfect optic fit this mounting plate is now available in two dedicated versions: one precision-cut for the RMR footprint and another specifically for the RMSc footprint. This allows you to seamlessly mount a wide variety of modern optics including the Hi-Lux TD-3C directly onto your top-ejection Winchester lever rifle. The base mounts directly to the two factory rear peep sight mounting holes on the left side of the receiver (spaced 0.400" apart). We eliminated the adjustment slots found on our legacy models replacing them with fixed counterbored holes. Combined with significantly tightened machining tolerances this ensures a rock-solid repeatable zero under heavy recoil. Every mount is precision CNC-machined from solid steel here in Torrance California.
