Holosun HE507K-GR X2 Green Multi-Reticle Reflex Sight

The Holosun HE507K-GR X2 is a compact open reflex sight built for subcompact and concealed carry pistols. It gives shooters a crisp green reticle, Holosun’s Multi-Reticle System, Shake Awake technology, and a durable black anodized aluminum housing in a small, carry-friendly package.

This model features a 2 MOA green dot, 32 MOA green circle, or circle-dot combination, allowing the shooter to choose the reticle that best fits their preference. The green reticle is easy to pick up quickly, and the compact K-series footprint makes this a strong option for slimline optic-ready pistols.

The HE507K-GR X2 also includes Lock Mode, which helps prevent accidental button changes once the optic is set. With long battery life, side battery access, and Holosun’s proven pistol optic design, this is a solid choice for defensive carry, range use, or upgrading a compact MRD pistol.

Fitment note: This optic uses the Holosun K / RMSc-style compact footprint and is a direct-mount style option for pistols cut for the Holosun 507K / Shield RMSc footprint, including the FN Reflex XL MRD. Always verify proper screw length and use the correct firearm-manufacturer supplied screws when required.
