MANY spools don't need the bolt engine removed in order to service the eyes or detents.
I bring this up since this thread is aimed at beginners, and you don't want beginners getting confused as to which part goes where. We've all seen the gun that has been completely reassembled the wrong way, so by limiting the number of parts taken off of the gun, the better.
