Sorry Guys, been super busy. I was not hitting the button on the side to release the bolt I was pulling back the charging handle and letting it go. Does that accomplish the same thing or do we get more force with the button on the side. I literally know nothing about these and I think I am going to build one to my specs so that I can actually put all the pieces together(instead of buying a complete lower). I don't think that will be too complicated. Is there anybody around Huntsvegas that would help me build the upper? I have an upper and lower (both stripped) that should make for a fun project to involve my sons in.
