The Lyman Receiver Peep Sights 66 is a rugged iron sight solution designed for hunters and shooters who rely on lever-action rifles and modern shotguns. If you're running a Winchester 94, Marlin 336, or similar flat-receiver platform and want to upgrade your aiming system without optics, this receiver peep sight mounts directly to your rifle's receiver for a fast, reliable sight picture. The 66 also fits SKS platforms, making it versatile across several popular rifle types.

Peep sights have been the choice of serious marksmen for generations—there's a reason they're still competition favorites and trusted by hunters in brush country where optics can fail. The Lyman 66 gives you simple, mechanical precision. Elevation and windage adjustments are made via 1/4 minute audible click micrometers, so you know exactly when you've dialed in your zero. The coin-slotted "stayset" knobs hold their position once locked, and there's a quick-release slide so you can swap the sight on and off the receiver without tools.

Two interchangeable aperture discs come with the sight: a larger hunting aperture for fast target acquisition in low light or brush, and a smaller target aperture for precision shooting at the range or from a rest. Switch between them in seconds depending on your hunting conditions or match requirements. For hunters and shooters who value simplicity, durability, and the speed of a peep sight, the Lyman 66 is a proven upgrade over factory sights.
