Holosun HE507K-GR X2 1x 0.58"x0.77" 2 MOA Green Dot/32 MOA Circle Reflex Sight - Black Anodized

The Holosun HE507K-GR X2 is a compact open reflex sight purpose-built for subcompact and micro-compact pistol applications. Part of the popular 507K series, this green dot variant pairs a high-visibility 2 MOA green dot / 32 MOA circle multi-reticle system with a rugged aluminum housing for fast target acquisition and precise aiming.

The sight features a 0.58" x 0.77" viewing window, 1x magnification, and effectively unlimited eye relief. The window uses multi-coated optics for a clear sight picture. A single CR1620 battery powers the unit, and both windage and elevation are user-adjustable in 1 MOA clicks. The black anodized aluminum housing carries a waterproof rating for reliable performance in adverse conditions.

The Multi-Reticle System allows the shooter to switch between a 2 MOA dot only, a 32 MOA circle only, or the combined dot-and-circle reticle without re-zeroing. At just 1.60" long and 1.0 oz, the HE507K-GR X2 is one of the lightest open reflex optics in its class, designed to fit the optics-ready slides of leading subcompact carry pistols.
