Well, upon further examination, I realized I will not be able to swap my receivers quite yet. A small piece, known as the hop up unit, comes in two forms: one-piece, and two-piece. You can see the difference by clicking on this link. I forgot that AGM, the manufacturer of my receivers, only comes with one-piece hop up capabilities. My gun, incidentally, has a two-piece hop up. So, while it was a nice thought, I will be unable to continue upgrading my gun until I can get my hands on a new hopup. Stay posted, though. I'll have pictures from an upcoming war soon.
Good evening,
