The ProWin AK 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.

Product Information:
Prowin Hop Up Chamber is a vast improvement over most Plastic HU units on the market. Overall, this item is worth every penny if it fits in your AK.

Requires substantial modding to work in Mag K variants like the Beta AK as well as the JG and *Echo 1 versions (Coming soon to market).

Product Information:
It's a prowin chamber.

-Looks nice

It would be a nice hop up if it worked. After quite a bit of modification, it still wouldn't fit depressingly. It's a very beautiful looking hop up and would've looked nice in my gun, but I expected it to fit. If you are to buy this hop up, be warned, it may not fit without extreme modification.
