The Holosun HS507C-X3 Red Multi-Reticle Reflex Sight (Model HS507C-X3-RD) is a premium open emitter pistol optic designed for competitive shooters and serious defensive users. Featuring Holosun’s advanced Multi-Reticle System (MRS) with a red reticle, solar power, Shake Awake technology, and a large viewing window, the HS507C-X3 delivers exceptional speed, versatility, and reliability. This updated X3 version builds on the success of the original HS507C with refined ergonomics and improved performance.
Red Multi-Reticle System (MRS)
The HS507C-X3 is equipped with Holosun’s Multi-Reticle System, allowing shooters to select between a precise 2 MOA dot, a 32 MOA circle, or both combined. The red-colored reticle provides outstanding contrast in bright daylight and against a wide variety of backgrounds. Whether you prefer a fine aiming point for precision or a larger circle for rapid target acquisition, the MRS gives you the flexibility to adapt the reticle to your shooting style and environment.
The Holosun HS507C-X3 combines a red multi-reticle system, solar power, and Shake Awake technology in a durable open emitter reflex sight.
Large Viewing Window
The HS507C-X3 features a large, clear viewing window that provides an expansive field of view. This design allows for faster target acquisition and better situational awareness, making it especially well-suited for competition shooting and defensive scenarios. The generous sight picture helps shooters maintain focus on the target while quickly aligning the reticle.
Solar Power with Shake Awake Technology
The HS507C-X3 utilizes Holosun’s advanced solar power technology. The built-in solar cells power the optic during daylight hours and help extend battery life. When ambient light is insufficient, the optic seamlessly switches to battery power. Combined with Shake Awake technology, the optic automatically turns on when motion is detected and powers down after a period of inactivity, ensuring maximum battery efficiency while keeping the sight ready when needed.
Durable Construction
Built with a rugged aluminum housing, the HS507C-X3 is designed to withstand the demands of daily carry and competitive use. It is waterproof, shockproof, and features a multi-coated lens that provides a clear, distortion-free image. The optic is also equipped with a protective hood that helps shield the emitter from impacts.
