Hop-Up chamber for M4 airsoft guns
Plastic hop-up chamber with a metal adjusting wheel designed for M4 / M16 series weapons.
This is a faithful design of the original ProWin hop-up chamber. Thanks to this, compared to the standard design, this chamber has a much more sensitive and precise setting of the pressure and also the rotation of BB´s. The package contains a complete chamber with an adjusting wheel. Made of high quality polymer. The control wheel is made of aluminum, made on CNC machines.
