Yeah that's all nice but the with the 747, if you're a tad left you can just push on its left side a little with your thumb and be dead on!I have to agree with @jkingrph , the 777 rear sight is a better tool than the IZH rear sight. However, the IZH comes with two rear sight blades with different size notches on the top and bottom so 4 different rear slot sizes. I have two different width front sight posts that are easy to change on the IZH so there are combinations that should work for most eyes. The 777 has an adjustable rear sight width which is pretty cool.
