Looking for Fill Valves (WE and KWA M4 mags)

[MultipleParadox]

As title state, I'm looking for some fill valves that will fit WE M4 mags, and others that will fit KWA Pmags.

Been looking around for a while and I couldn't find any good sources. The only thing I found was eHobby having the stock WE valves, out of stock.

Edited:
(I have just been informed by Duy that Madbull valves from Airsoftparts.ca will fit the old gen of WE mags. I got 4 Gen2 conversion kit I will need valves for, I guess...)


Thanks

PS: Thanks again Duy for the uber-fast response; Airsoftparts has the best service ever guys, buy from him!

I can confirm that they also fit V2 mags (I have replaced two so far).
