RWTF, ok. Not sure about the batshit stuff. However when my stud is screwed fully into the receiver the milled head of the stock (my replacement) does not come anywhere near fitting flush into the back of the receiver. Wide gap at top of receiver. With the trigger guard tang up tight to the wood. With the stud removed of course the stock fits just fine, snug with complete mating of metal to wood. Put the stud in, no fit at all. I should add that my stud is angled down when fully inserted. These stocks appear to be machine made without hand fitting. ???
