Holosun 507C X3 Red Open Pistol Sight 2 MOA Dot & 32 MOA Circle

The Holosun HS507C-X3-RD introduces a refined evolution of the classic 507C platform, combining a reinforced housing, updated branding, and advanced brightness management in a compact optic built for modern pistol setups. Designed around the popular RMR footprint, the X3 series delivers a low-profile solution optimized for everyday carry, duty use, and consistent range performance. At the center of the HS507C-X3-RD-MRS is Holosuns Multi-Reticle System, giving shooters the flexibility to run a precise 2 MOA dot, a 32 MOA circle, or a combined reticle to match speed or precision needs. A forward-facing photodiode works with Solar Failsafe to automatically adjust brightness as lighting conditions change, while manual brightness control with memory and lockout modes provides full control when needed. Powered by a CR1632 battery with up to 100,000 hours of runtime on setting six, the HS507C-X3-RD-MRS is engineered for long-term reliability. With Shake Awake technology and a rugged 7075-T6 aluminum housing rated IP67, it delivers dependable performance without added bulk or complexity. For shooters who want a modern pistol optic that blends versatility, durability, and smart power management, the HS507C-X3-RD-MRS sets a new standard in performance optics.
