ProWin M4 Hop Up Chamber

The Prowin M4 Hop Up Chamber is a great upgrade to your AEG's standard plastic, or weakly cast metal hop up chamber.

Aluminium CNC fabricated Hop Up chambers are known to give a much better air seal than the standard Hop Up chambers built into a new airsoft replica.
However, many cast metal Hop Up Chambers have weak spots in the metal caused by the casting process, but this problem is completely eliminated with the ProWin Chamber.

This Hop Up Chamber is made entirely of Aircraft Grade Aluminium, which means it is both lightweight and durable, and the bright blue colour helps give your AEG a custom look.
