Holosun HE507C-X3-GR-MRS is a premium open reflex sight designed for pistol platforms using the RMR footprint. It features a bright green Multi-Reticle System (MRS), durable construction, and advanced power management, making it ideal for everyday carry, duty use, and dynamic shooting.

Multi-reticle versatility for any situation

The Multi-Reticle System allows you to switch between a precise 2 MOA dot, a 32 MOA circle, or a combination of both. This gives you flexibility – use the dot for precision at distance, the circle for fast target acquisition, or both for maximum control.

Green dot for enhanced visibility

The green reticle is easier to pick up for many shooters, especially in bright daylight or high-contrast environments. It helps reduce eye strain and improves target focus during extended shooting sessions.

Always ready with smart power features

Shake Awake technology activates the optic instantly when movement is detected and powers it down when idle, preserving battery life. The system remembers your last brightness setting, so it’s always ready exactly how you left it.

Adaptive brightness & solar backup

Automatic brightness adjustment uses a forward-facing sensor to adapt to lighting conditions in real time. Solar Failsafe ensures the reticle remains visible even if battery power is low, providing extra reliability in critical moments. :contentReference[oaicite:0]{index=0}

Battery access without losing zero

The side-loading CR1632 battery tray allows quick replacement without removing the optic from your slide. This means no re-zeroing and less downtime between sessions.

Durable and duty-ready construction

Built from strong aluminum and designed to withstand harsh conditions, the optic offers IP67 water resistance and high vibration resistance for dependable real-world use. :contentReference[oaicite:1]{index=1}
