Need to upgrade your KWA/KSC G series GBB, this is the part for you. If you are new to airsoft I suggest you find someone with good experience to install it.
Nice upgrade. Costly but worth it. Will replace the stock plastic valve, which will eventually fail. Better than airsoft surgeon floating valve. Best I have used.
This thing is so nice!!! It makes my Taiwan full metal g19 shoot so smooth and controlled. it conserves gas too. great b/c the original plastic ones dont last long at all...
A must have for KWA / KSC ATP or Glock owners. Factory mass product guns can't give you CNC nice parts such as this one! Treat yourself to this $16 awesome part for a smoother firing G17!!
