Green vs red - Holosun HE510C Elite 1x 2MOA Reflex Green Dot Sight

I am glad that I waited for the green dot. The mounting was easy and secure on my PTR 91 PDW. I have the pre rail model and use a claw mount to attach optics. The .308 shock did not throw off the POA/POI. Sighting in was only a few click and then it was dead on target. Visibility is great with the green against all targets in an outdoor and open environment. I enjoy the heads up open viewing provided by this optic in comparison to the TRS25 and the Athlon 1x4 I previously utilized. The sight appears bulky but once mounted it really is not significant.
