I came across these sights called Night Fision night sights the other day on YouTube and so I decided to give them a try. I have to say that I am extremely impressed with them. They are very bright and easy to see. I will be switching all my night sights to these in the near future. The only sight I have personally seen come close to them are TFO’s. They seem to be made well and are made in America! The font dot is pretty big too. It looks similar to the XS big dot sights. Supposedly these are the brightest on the market. I have TFO’s, Ameriglo, and glock night sights and these blow the all away with the exception of the TFO’s. But they are brighter than those. If you haven’t seen them check them out.
