Lyman 66LA Receiver Sight for Marlin 336/1894 - Aluminum Blue

The Lyman 66LA receiver sight brings classic precision to your Marlin 336 or 1894 lever-action rifle. If you shoot a flat-receiver lever gun and want to move beyond factory iron sights, this aluminum-bodied aperture sight mounts directly to your receiver and gives you the accuracy boost that counts at the hunting camp or range. It's the kind of upgrade that turns a good rifle into one you actually trust at distance.

Built for hunters and shooters who appreciate straightforward, reliable glass-free aiming, the 66LA uses a dual-aperture system: a larger hunting disc for quick target acquisition in the field and a smaller target aperture for precision work on the bench or at the range. The sight's quick-release slide design means you can swap between hunting and target shooting without permanently committing to one setup. Windage and elevation adjustments click at 1/4-minute increments, giving you repeatable adjustments you can dial in with confidence. The knobs are coin-slotted and feature a "stayset" design—once you've zeroed, they stay put.

Lyman receiver sights have armed American hunters for decades. This aluminum blue-finished version fits the classic lines of lever-action rifles while delivering the functional accuracy of a quality aperture sight. If your Marlin 336 or 1894 deserves better than open sights, the 66LA is a no-nonsense choice.
