Primary Arms SLX RS-10R Mini Reflex Sight - 3 MOA Dot - 507c Footprint

The Primary Arms SLx RS-10R Mini Reflex Sight brings the proven RS-10 platform to the widely adopted Holosun 507c footprint, expanding compatibility across a broad range of pistol slides, mounts, and aftermarket accessories without sacrificing any of the features that made the original RS-10 a standout value. At the center of the RS-10R is a 3 MOA dot optimized for handgun use — precise enough for accurate shooting at distance, but fast to acquire at close range. The 23x19mm multi-coated lenses deliver a clear, distortion-free window, and the reticle spans from dedicated low-light brightness levels through full daylight intensity, covering every shooting environment without adjustment guesswork. Battery life is a defining strength of this optic. A side-loading battery compartment allows replacement without removing the optic from the slide, and the rated 40,000-hour runtime means extended use between changes. AutoLive motion-sensing technology further extends that runtime by powering the dot down automatically when the optic is stationary and snapping it back on instantly when motion is detected — no manual switching required. The housing is machined from rugged 7075 aluminum, keeping the total weight at just 1.1 oz. Push-button controls are simple and accessible, and the included M1913 Picatinny rail mount provides an out-of-the-box mounting option for non-milled platforms. Backed by a comprehensive lifetime warranty, the RS-10R delivers serious functionality at a practical price point.
