Ncstar tactical blue dot sight - NcSTAR Micro Tactical Green Dot Sight w/ On/Off Switch

I purchased this sight for my fiancé’s Roger mk iv .22/.45 and the only complaint I have is the size of the window. But then again, it’s a .22 so you can shorten your grip and see the dot perfectly. I will say this, bc some people may be like me and will find this interesting... BLUE DOTS ARE MEANT FOR PEOPLE WITH COLORBLINDNESS. It’s not just for looking cool. It’s a little harder to see outside, but it’s meant to help shoot at night if absolutely necessary. Overall, great sight, stellar price
