Holosun 510C

The HS510C Open Reflex Circle Dot Sight has an open frame for a wide sight picture. It is powered by solar cell under normal usage, and a back-up battery to supplement power requirements in low light conditions. The reticle can be switched between a 65 MOA circle with 2 MOA dot, a 2 MOA dot only, or a 65 MOA ring only at the push of a button. Better yet, the same LED projects both reticles, so no re-zeroing is necessary. Key Features: Multiple reticle options: Choose between a 2MOA dot, a 65MOA circle, or both! Parallax free and unlimited eye relief Titanium-alloyed, shock resistant hood: Built to withstand the rigors of real-world use Quick detach mount: Easily detach or reattach this optic with the QD mount.
