Ther nice look good buuuuut.... - Battle Arms Development Enhanced AR Lower Parts Kit

Ok I realy wanted to try em out. Only problem I had was with the bolt catch it seemed to be slightly thicker then mil spec causing it to stick and not do its job.yes I installed spring and detent yes I know the bolt catch relies on the follower in a magazine to operate but the dang thing was stuck holding the follower down. I've contacted battle arms development and they've questioned everything first if it's even installed properly I've shown them proof on video and pics of theres vs mil spec and mil spec works just fine. Kinda hoping mine is just flawed and send me another that's actually works because they look and feel tons better then mil spec.
