Pickup currently unavailable at Skirmshop Spain
The ProWin M4 / M16 CNC hop-up chamber is a major upgrade over the stock plastic or weak cast metal hop-up chamber in your AEG. Metal hop-up chambers are known for providing a better air seal against the AEG gearbox and feeding much more smoothly than plastic chambers. However, many cast metal hop-up chambers have weak points in the metal due to the casting process, but this issue is completely eliminated with the ProWin chamber. This hop-up chamber is fully CNC machined from aircraft-grade aluminum, meaning it is lightweight and durable, and the bright blue color gives your AEG a custom look.
