Granite Ridge's Take
The Holosun 510C is a wide-window open reflex sight built for carbines, PCCs and other rail-mounted platforms. It is a fantastic do-all optic that's great for any situation without breaking the bank. The 510C combines Holosun’s Multi-Reticle System with Solar Failsafe, Shake Awake, a protective titanium hood and an integrated quick-detach co-witness mount, all for a great value.
Buying & Compatibility Notes
Choose red or green based primarily on your reticle-color preference; the core 510C platform and mounting format are otherwise the same. The selectable reticle system includes a 2 MOA dot, 65 MOA circle, or circle-dot combination. If you want magnification as well, the 510C pairs naturally with the Holosun HM3X magnifier.
