Holosun 510C 65 MOA Circle Dot Open Reflex Sight

The Holosun 510C is an open reflex sight built for long guns, with a wide open frame that gives a large, clear sight picture on carbines, pistol caliber carbines and shotguns. The same LED projects all three reticles, a 65 MOA circle with a 2 MOA dot, the dot alone, or the circle alone, so switching between them needs no re-zero.

The aluminum body is protected by a titanium hood that shrugs off bumps. Power comes from a CR2032 battery rated up to 50,000 hours, with Solar Failsafe as a backup and Shake Awake to shut the LED off at rest. It is parallax free with unlimited eye relief, and it comes on a QD absolute co-witness riser mount for 1913 Picatinny rails.
