I didn't like the fact that I had to give up my rear irons, but I did try the LT100 and did not like it. I like were the ROC puts my cheek when looking down. This setup is one fine piece of equipment!!! You can tell just by holding it that its built. I sold my eotech 553 with magnifier to get this setup and I have to say with how clear the optics are I don't miss the eo, but when I'm looking around in a small room I do miss my eo? I mean we are talking point and shoot ranges anyway, but the eo was awsome for that! Maybe in time I will add a doc or something? For now I'm good. I just need to get the funds together to finish the shock. I'm looking into a sopmod if its still around when the money comes? Here are the pics! The pic of the retical could be better but I'm limited to space and the camera.
