Luth-Ar Retro A1 Rear Sight Assembly With Retro Windage Knob

The Luth-Ar Retro A1 Rear Sight Assembly brings classic AR ergonomics and proven reliability to your modern rifle build. If you're running an AR-platform gun and want iron sights that feel authentic to the platform's heritage while delivering solid field performance, this rear sight assembly delivers both—without the guesswork of aftermarket adjustments. The retro windage knob design makes zeroing intuitive and repeatable, whether you're at the range or in the field.

This is a complete rear sight assembly, not just a loose component. It arrives with all the internal parts you need for installation: the windage drum, detents, spring, aperture, windage screw, roll pin, and flat spring. That means you get a matched set engineered to work together rather than sourcing parts separately and hoping they cooperate. Luth-Ar manufactures these to tight tolerances, so fit and function are consistent shot to shot.

The retro aesthetic pairs naturally with period-correct builds, but the practical design works just as well on any AR carbine where you want simple, reliable iron backup or primary sighting. No batteries, no glass to break—just steel, spring tension, and the fundamentals that have worked for decades. If your rifle already sports a flat-top receiver ready for sights, this assembly bolts into place and gets you shooting.
