Holosun 507C X3 [red]

This red dot uses the Trijicon RMR footprint standard.

Key specifications

Holosun HS507C-X3-RD-MRS is an advanced open reflex red dot built for pistol platforms using the RMR footprint. It combines a versatile multi-reticle system, durable aluminum construction, and intelligent power management to give you full control over speed, precision, and reliability in any shooting scenario.

One optic, multiple aiming styles

The Multi-Reticle System lets you switch between a precise 2 MOA dot, a fast 32 MOA circle, or a combined circle-dot reticle. Whether you prioritize accuracy at distance or rapid target acquisition up close, this optic adapts instantly to your shooting style.

Faster target acquisition under pressure

The large circle option helps you pick up the reticle faster, especially during dynamic shooting or recoil. When you need precision, the clean 2 MOA dot keeps your aiming point sharp and unobstructed.

Smart brightness and solar backup

A forward-facing photodiode automatically adjusts brightness based on ambient light, while Solar Failsafe ensures the reticle remains visible even in changing conditions. Manual control with memory and lockout gives you full control when needed. :contentReference[oaicite:0]{index=0}

Always ready, always efficient

Shake Awake technology powers the optic on instantly when movement is detected and turns it off when idle, dramatically extending battery life. With up to 100,000 hours on a CR1632 battery, you can rely on long-term performance without constant maintenance. :contentReference[oaicite:1]{index=1}

Battery change without losing zero

The side-loading battery tray allows quick replacement without removing the optic from your slide, saving time and preserving your zero.

Built for demanding use

The 7075-T6 aluminum housing delivers high strength while keeping weight low. Combined with IP67 water resistance and strong recoil resistance, this optic is designed for everyday carry, duty use, and intensive range sessions. :contentReference[oaicite:2]{index=2}
