This is my L.C. Smith Ideal with a Nydar sight mounted. I've shot it quite a few times and once you get used to holding your head way off the stock it works well. In fact, with a properly designed stock it would probably work great. I think I read somewhere that the guy that put these into production was a gunner on a WW2 airforce bomber and the machine guns used a reflex sight like this. I'm leaving it on. At least I won't have to worry about filling the screw holes.
