The ProWin M4 / M16 CNC Hop Up Chamber is a great upgrade from your AEG’s stock plastic, or weak cast metal hop up chamber. Metal hop up chambers are known for providing a better air seal against the AEG’s gearbox, and feeding much more smoothly than plastic chambers. Many cast metal hop up chambers, however, have weak areas in the metal from the casting process, but this problem is completely eliminated with the ProWin chamber. This hop up chamber is machined completely out of aircraft grade aluminum, meaning it is both lightweight and durable, and the bright blue color helps give your AEG a custom look.
