Holosun HS507K X2 1x 2 MOA Red Dot/32 MOA Circle Reflex Sight - Black Anodized

The Holosun HS507K X2 is an open reflex optical sight purpose-built for subcompact pistol applications. Part of Holosun's 507 series, this compact red dot features a rugged housing with a black anodized finish and a clear window measuring 0.58" x 0.77", giving shooters an unobstructed sight picture at 1x magnification with unlimited eye relief.

The multi-reticle system pairs a crisp 2 MOA red dot with a surrounding 32 MOA circle, allowing the shooter to run a precise dot, a fast circle-dot, or a circle-only configuration depending on the task. The optic is powered by a single CR1632 battery rated for up to 50,000 hours of runtime. Lenses are multi-coated for clarity and glare reduction, and the housing is sealed to a waterproof standard for real-world carry conditions.

At just 1.60" long and 1.70 oz, the HS507K X2 keeps weight and footprint to a minimum on optics-ready subcompact slides. 1 MOA per-click windage and elevation adjustments make zeroing straightforward. This is the X2 revision of Holosun's popular HS507K, an excellent match for concealed-carry and backup pistol platforms.
