Kwa mp7 MAG
 

Whenever i fill up the mag for the kwa mp7 gas starts spewing from the fill valve like the gas isnt even making it into the mag, but im not sure of why. It will hold a little bit of gas,. Maybe about 5-10 shots. And it does not seem to make any hissing noises like a leak when i put it to my ear. Im filling the mag just like anyother of my guns . is the mp7 different in anyway?

Valve might be loose, might be cracked?

Get a replacement valve and o-ring/seals from KWAUSA pro shop~!

It could possibly be loose i just got it from another asc member so it could of happended during shipping. What could i use to tighten it?
