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.

• 2 MOA dot and a 65 MOA ring

510C red dot sight.
I mounted this sight on a S&W Model 41. Fine sight with so many features and it worked great out of the box. Like the the 2 MOA dot for target.  For steel need option for larger MOA dot.

Outstanding Engineering, Quality and Price
This is the third Holosun 510C that I've purchased.  I've replaced my EoTech circle-dot reflex sights with these.  The features and circle clarity are superior, the quality is excellent and the price is about 60% of the equivalent EoTech model.  The solar cell works great and allows the inexpensive backup wafer battery to last over a year.
