Spartacus: I've tried it full assembled and it does the same thing but I understand what you mean. The gun cycles just fine if I don't pull down but it seems like i have to purposely try not to pull down because if I just yank on it like I do an ak, I can sometimes feel it. The BHO seems to function just fine. I will be range testing it this Sunday before I do anything else. I will als get some pics of what I was talking about up. Wanted to do that yesterday but didn't have the time. Also, I just wanted to say thanks for all the input guys.
