The SLx RS-10R Mini Reflex Sight combines the value and innovation of the RS-10 with the Holosun 507c footprint, increasing compatibility with pistol slides and mounts. This optic offers an ultra-bright reticle usable in all lighting conditions, 23x19mm multi-coated lenses, night-vision compatibility, and an ultra-long battery runtime with a side-loading battery slot. In addition to the already impressive battery life, the RS-10R features AutoLive technology that automatically turns off the dot when not in use and turns it back on immediately when motion is detected, further improving battery life. As pistol-mounted reflex sights continue to grow in popularity, the SLx RS-10R offers a lot of functionality.
