The Holosun HE507C-X3-GR advances the 507C platform with a refined X3 housing and the enhanced visibility of a crisp green reticle. Designed for modern pistol setups, it delivers a low-profile optic solution that balances everyday carry practicality with consistent, dependable performance on the range. At its core, Holosun’s Multi-Reticle System gives shooters the flexibility to select a precise 2 MOA dot, a bold 32 MOA circle, or a combined reticle to suit speed-focused or precision-driven shooting styles.

A forward-facing photodiode paired with Solar Failsafe automatically adjusts brightness as lighting conditions change, while manual brightness control with memory and lockout modes provides confident control in any environment. 

Powered by a CR1632 battery offering up to 100,000 hours of runtime and supported by Shake Awake technology, the HE507C-X3-GR-MRS is engineered for long-term reliability. Its rugged 7075-T6 aluminum housing, rated IP67, ensures durability without adding unnecessary bulk. For shooters seeking a modern, carry-ready optic with enhanced visibility and adaptable reticle performance, the HE507C-X3-GR-MRS delivers clarity, confidence, and consistency with every draw.
