I just picked up an A2 stock for my build but it has a slight gap between it and the lower. The screw is tightened all the way, I don't know if there's different size spacers available ? I don't think they're supposed to have that end plate right?
check inside the stock for anything the previous owner may have stuffed in there to allow room for a m4 style end plate. there maybe a washer or something in the stock itself.
