Ok figured out what the problem was with the front sight. I mail the wrong one to my SOT. It was a late war model. I'm ordering the one from DK and it should be correct. I'm having 7 builds of different MP44s and sometimes things get mixed up. On the bolt my SOT is going to mill a bit off on the ears to get a better fit. It will make the bolt closer to the original bolt dimension and hook up better with the ears on the original op. rod.
