Swamp Fox Kingslayer Micro Reflex Sight Green Circle Dot

The Swamp Fox Kingslayer Micro Reflex Sight with Green Circle Dot reticle is a compact open reflex optic engineered for rapid target acquisition across pistol, rifle, and shotgun platforms. Built on the proven RMR-compatible footprint for slide-mounted applications, the Kingslayer delivers three reticle options—including the green circle dot—allowing operators to engage targets with both eyes open while maintaining focus through to the target. This configuration is critical for close-quarters work and dynamic shooting scenarios where speed and situational awareness outweigh magnification.

The optic weighs just 0.6 pounds and measures 3.9 x 3.3 x 5.1 inches, making it one of the smallest reflex sights available without sacrificing lens quality or reticle visibility. The scratch-resistant anti-glare lens coating cuts down on glint and reflections in bright conditions—essential for tactical applications where flash signatures matter. Waterproof and fog-resistant construction ensures the sight performs in wet environments and temperature swings common to field operations. For rifle and shotgun mounting, the Kingslayer ships with a low-profile 1913 Mil-Std Picatinny mount already installed, eliminating additional purchase and installation steps.

Law enforcement officers, military personnel, and competitive shooters favor micro reflex sights for close-range pistol work, home defense setups, and precision rifle applications where a compact footprint is non-negotiable. The green circle dot reticle excels in low-light conditions and against varied backgrounds, offering better contrast than traditional red dots for some shooters. The Kingslayer's compatibility with standard RMR holster ecosystems and existing Picatinny mounts makes it a drop-in upgrade for established platforms without requiring new accessories or manipulation procedures.
