Holosun 507C X2 Open Reflex Sight MRS Multiple Reticle - Red Reticles (RMR Footprint)

Upgrade your optic-ready pistol with the Holosun HS507C X2 Open Reflex Sight, a high-performance red dot engineered for reliability, speed, and precision. Designed for full-size handgun platforms, this optic features Holosun’s Multi-Reticle System (MRS), allowing you to switch between a 2 MOA dot, 32 MOA circle, or circle-dot combo for maximum versatility in any shooting environment.

Built from durable 7075-T6 aluminum, the 507C X2 is designed to withstand demanding use while maintaining a lightweight profile. Its Solar Failsafe™ technology ensures the optic remains operational even if the battery fails, while Shake Awake™ automatically powers the unit on with motion and off when idle to extend battery life.

The X2 model introduces Lock Mode, preventing accidental setting changes during carry or operation—making it ideal for duty, defensive, or competition setups. The side-mounted CR1632 battery tray allows easy replacement without removing the optic, keeping your zero intact.

With a parallax-free design, unlimited eye relief, and crisp multi-coated glass, the HS507C X2 delivers fast target acquisition and consistent accuracy at close to mid-range distances. Compatible with the industry-standard RMR footprint, it fits a wide range of optic-ready slides including Glock® compatible platforms and other full-size handguns.
