Holosun 507C X3, 32 MOA Ring & 2 MOA Gold Dot, RMR Footprint, MRS Reticle, Side Battery, Solar Failsafe - 507C-X3-GD-MRS

The Holosun 507C-X3 updates the classic 507C with a refined, modern housing and engraved Holosun logo while keeping the proven performance shooters rely on. Built to the popular RMR footprint, the 507C-X3 mounts cleanly to a wide range of full-size pistols and adapter plates, making it an easy upgrade for everyday carry, duty, or range use.

At the core of the optic is Holosun’s Multi-Reticle System (MRS), allowing you to choose between a precise 2 MOA dot, a fast 32 MOA circle, or a combined circle-dot reticle. Available in Red, Green, or Gold, the reticle options let shooters tailor visibility to personal preference and changing lighting conditions.

The 507C-X3 features Solar Failsafe and a forward-facing photodiode that automatically adjusts brightness as ambient light changes, while manual brightness control with lockout and memory modes ensures consistent settings when you want full control. With up to 100,000 hours of battery life from a CR1632 battery, this optic is built for long-term reliability.

A low-profile, compact design keeps the optic holster-friendly, while the rugged 7075-T6 aluminum housing, IP67 waterproof rating, and 5000G vibration resistance ensure the 507C-X3 can handle hard use. The result is a familiar optic with updated ergonomics, clean styling, and dependable performance.
