The highest quality hop-up chamber made by a  known and renowned ProWin company. The chamber was made entirely from a single block of aluminum with the use of precise CNC machines.

The use of a ProWin aluminum chamber will allow for the achievement of much better stability and tightness of the system than at stock, which directly results in better performance and even increase the FPS values.
