 Product Description

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.

  3. Great Hop up chamber

    Posted by Julius Blahovsky on 2nd Oct 2014

    Straight forward fit into my G&P M4 moe.
    Worked great with the original nozzle.
    Worked again great when used with the P* FE.

    I have used the PDI raven 303mm barrel a and systema energy bucking with very good results.

    on 120psi blue nozzle 407fps with 0.20s and 330 fps with 0.40s.

    Great air seal.
    You cannot go wrong with this chamber.
