Product Description The Primary Arms SLx RS-10R 1x23mm Mini Reflex Red Dot Sight is an upgraded evolution of the original RS-10, engineered to deliver exceptional performance in a compact, lightweight package. Built on the trusted SLx platform - known for innovation, reliability, and value - the RS-10R features compatibility with the widely popular RMR and Holosun 507c footprints, making it exceptionally versatile for mounting on modern pistol slides and aftermarket mounts. The optic utilizes a bright 3 MOA red dot reticle powered by LED illumination, offering both daylight-bright and night-vision-compatible brightness levels for all-condition use.
