The Holosun RONIN-HE507COMP is a high-performance open reflex sight built for everyday carry, competitive shooting, and tactical operations. Designed in collaboration with Tu Lam of Ronin Tactics, this specialized optic reflects the durability and precision required by real-world professionals and elite competitors alike. At the core of the RONIN-HS507COMP is Holosun's Multi-Reticle System (MRS), allowing shooters to seamlessly switch between a precise 2 MOA dot, a 32 MOA circle, or a combination of both. This flexibility enhances performance in both close-quarters engagements and precision shooting, adapting instantly to your environment and application. The optic's large competition-grade viewing window (1.1" x 0.87") provides an expanded field of view, improving target acquisition speed and situational awareness. Powered by a 650nm Super LED, the reticle is sharp and vivid, backed by an impressive battery life of up to 50,000 hours on setting 6. Designed for reliability in any condition, the RONIN-HS507COMP features Shake Awake technology, Lock Mode to prevent accidental adjustments, and 12 brightness settings—including 8 for daylight and 4 night vision-compatible levels. The CR1632 battery is housed in a side-mounted tray for quick, tool-free replacement without removing the optic from your firearm. Built from rugged 7075-T6 aluminum with a durable black anodized finish, the RONIN-HS507COMP is IP67 waterproof, vibration-resistant up to 5000G, and engineered to thrive in demanding environments. The sight is also RMR footprint compatible, ensuring easy mounting on a wide variety of full-size and compact handgun platforms.
