Holosun 510C Red Dot Holographic Sight

The Holosun HS510C Open Reflex Circle Dot Sight features an open frame design that delivers a wide sight picture. Power comes from a solar cell during normal usage, with a back-up battery to maintain operation in low light conditions. The reticle offers three switchable options—a 65 MOA circle with 2 MOA dot, a 2 MOA dot only, or a 65 MOA ring only—all selectable at the push of a button. Since a single LED projects both reticles, switching between configurations requires no re-zeroing.
