I am trying to install my new metal hop up unit into my M16, and I have hit a little bit of a snag. I know I have to take out the piece where the BB's would enter from the mag but there is a plastic piece the come out of the gear box that gets in the way of folding the gun back down.
Do I have to take that piece out of the gear box? or do I have to put the metal Hop Up over top of that plastic piece? or any other way to get it together.
