This Holosun combo pairs the wide-view HS510C-GR reflex optic with the HM3X 3× magnifier, giving you instant 1× speed plus the ability to extend to 3× without removing your optic. The HS510C’s Multi-Reticle System (2 MOA dot / 65 MOA circle / circle+dot), Solar Failsafe, and Shake Awake deliver long runtime and rock-solid reliability, while the HM3X provides crystal-clear 3× magnification with generous eye relief and a rugged QD flip-to-side mount. Both units are built in durable aluminum housings and carry IP-rated water resistance for real-world use. The combo includes mounting hardware and a protective case for transport and storage.
Ideal for carbines, patrol rifles, and modern sporting platforms where fast target acquisition and flexible engagement ranges are required.
