Holosun HE510C-GR Open Reflex Red Dot Sight - Green Multi-Reticle System & QD Picatinny Mount
The Holosun HE510C-GR is a 1x open reflex sight built around a wide viewing window and a green Multi-Reticle System (MRS). Reticle selections include a 2 MOA dot, 65 MOA circle, or circle-dot combination for fast transitions or a cleaner aiming point.
Features include Solar Failsafe, Shake Awake, a side-loading CR2032 battery tray, and an integrated quick-detach Picatinny mount for Picatinny rails (co-witness height depends on installed spacer/installation). The housing combines aluminum construction with a titanium protective hood and is rated IP67 for weather resistance.
