Lyman 66 Receiver Peep Sight

The 66 sight is designed for mounting on flat receivers, such as lever action rifles, like the Winchester 94, Marlin 336 or modern shotguns. Features include 1/4 minute audible click micrometer adjustments for elevation and windage, quick-release slide, coin-slotted “stayset” knobs and two interchangeable aperture discs (large hunting aperture and small target aperture) for any shooting condition. – Lyman
