Primary Arms SLx RS-10R 3 MOA Red Dot Sight - RMR Footprint

Primary Arms SLx RS-10R Mini Reflex Sight – RMR/507C Footprint

The SLx RS-10R Mini Reflex Sight takes everything you loved about the original RS-10 and upgrades it with a Holosun 507C/Trijicon RMR footprint—unlocking broader slide and mount compatibility for pistols and carbines alike. Designed for duty-grade performance, it combines a rugged 7075 aluminum body with crystal-clear 23x19mm multi-coated glass for a clean sight picture in every lighting condition.

Built for speed and precision, the daylight-bright 3 MOA dot excels in bright sun, while night vision-compatible settings keep you on target after dark. The side-loading CR1632 battery delivers up to 40,000 hours of runtime, and with AutoLive® motion activation, your dot is ready the instant you are—saving battery life without slowing you down.

Weighing just 1.1 ounces, the RS-10R disappears on the slide until you need it, while intuitive push-button controls make adjustments fast and simple. Whether you’re upgrading your EDC pistol or adding a fast sighting option to a rifle or shotgun, the RS-10R blends durability, innovation, and unbeatable value—backed by Primary Arms’ comprehensive lifetime warranty.
