The Holosun HS510C-GR & HM3X combo kit pairs a rugged open reflex sight with a flip-to-side magnifier to deliver fast target acquisition and extended-range capability in one versatile package. The HS510C-GR features a titanium protective hood and Holosun’s green Multi-Reticle System, allowing users to switch between a precise 2 MOA dot, a large 65 MOA circle, or a combined circle-dot reticle for rapid engagement at close to mid-range distances. Solar Failsafe and Shake Awake technologies enhance reliability and battery efficiency, while the quick-detach Picatinny mount enables secure, repeatable installation. The included HM3X 3× magnifier mounts behind the optic and flips out of the way when not needed, providing clear magnification and generous eye relief for longer-range shots. Housed in a protective hard case, this combo is well suited for tactical, competition, and general-purpose rifle setups.
