The Luth-AR AR-15 A1 Rear Sight Assembly adds that extra touch of authenticity to your retro build. It is designed to look and act the part of the original-style rear sight on your reproduction AR-15 / M16A1. While the modern AR offers various improvements there’s nothing wrong with having an appreciation for Eugene Stoner’s original design. The Luth-AR reproduction A1 Rear Sight Assembly features all-steel construction and non-reflective a matte black finish. It includes the aperture, windage drum, detent, detent spring, windage screw, and roll pin, so it is ready to install on your next build - or to give an existing rifle a different look.

The A1 rear sight features two apertures, one unmarked, for closer targets, and one marked "L" for long range.
