Primary Arms Micro Reflex Sight Green Dot Reflex Sight 21mm Objective 3 MOA Green Dot Anodized Finish Black RMSc Footprint

The Primary Arms Micro Reflex Sight Green Dot Reflex Sight with 21mm objective lens and 3 MOA green dot is purpose-built for shooters who demand a compact, fast-acquisition optic without compromise on reliability. Whether you're running a pistol-caliber carbine, shotgun, or short-barreled rifle platform, this reflex sight delivers the speed advantage that matters in defensive and tactical applications. The RMSc footprint compatibility ensures seamless integration with modern slide-mounted and Picatinny rail systems, making it an ideal choice for law enforcement, military personnel, and civilian tactical shooters alike.

Built with a hardcoat anodized finish in black, the Primary Arms reflex sight withstands the rigors of duty use and harsh environments without degradation. The 3 MOA dot subtends tight enough for precision work at 25 meters while remaining visible enough for rapid target acquisition at close quarters—the proven sweet spot for working distances in real-world engagement scenarios. The 21mm objective lens gathers sufficient ambient light for reliable dot brightness across varying lighting conditions, and the RMSc footprint standardization means you're investing in an optic that works across multiple platforms without additional mounting adapters.

This sight benefits operators who prioritize target speed over maximum magnification—those running close-quarters defensive platforms or duty rigs where 0-25 meter engagements dominate. Installation is straightforward on any RMSc-compatible slide or rail interface, with no gunsmithing required. The green dot reticle is preferred by many shooters over red for lower-light and indoor environments, making it particularly valuable for home defense, patrol work, and tactical team deployments where peripheral lighting is unpredictable.
