Primary Arms SLX RS-10R Features The Primary Arms SLX RS-10R is built from 7075 aluminum a lightweight yet rigid housing material that holds up to the recoil and rough handling that a duty or range pistol sees day to day. Its RMR mounting footprint drops directly onto any slide cut to that standard making it a simple upgrade for shooters already running an RMR footprint optic. A 3 MOA green dot reticle viewed through a 23x19mm multi-coated aperture gives a fast precise aiming point that stays visible across a wide range of lighting conditions. The green dot in particular offers strong contrast and visibility for shooters who prefer it over a traditional red reticle. AutoLive Motion Sense Technology automatically powers the dot down after a period of inactivity and instantly reactivates it the moment the sight detects motion extending battery life without asking the shooter to remember to shut it off. Side mounted illumination controls provide 11 total brightness settings two of which are night vision compatible so the RS-10R adapts from bright daylight to dark low light environments. The anodized black finish protects the housing against wear while keeping the optic s profile low and unobtrusive. For shooters seeking a rugged long-running reflex sight built on the widely supported RMR footprint the Primary Arms SLX RS-10R is available for sale at GrabAGun.
