Hey guys,

I need some help finding an upgrade valve for this:

I cant seem to find one that actually fits. So if there are any doctors out there that have experience with this mag let me know. It seems most valves do not fit this!

Are you looking for a hi flow valve?

Yes, im looking to upgrade the fps for it.

Why don't you upgrade your gun's flute/rocket valve or other internal gas flow parts instead?

WEll this is what im trying to figure out. I really need help from a gun doctor. Im attempting to import a gun that is not available in Canada or the States. The gun shots at between 350-363 fps. Extending the barrel doesnt work as there are no barrels that fit the gun. The guys have tried several things to upgrade the fps but nothing seems to be working. I will try a different mag tonight tho, as they just got some stock in.

Another question is...how hard would it be to DOWNGRADE a gbb? Keep in mind that valves and parts are like non existent atm. And i'm only talking about a marginal drop of like 10-15 fps.

The two mags im working with are:

If the gun uses this mag, it most very likely uses the same rocket valve/adjustable valve as the WA M4 GBBR system, since the nozzle has to be at the same place and the same shape.

But you could drive to a store that sells the gun you want (in the states) with a battery Dremel and cut open part of the rocket valve. Don't forget to buy replacement too.

GBBs can be boosted in FPS by allowing more air through before the blowback cycle.

Yah, so the guys at the shop tried this and it doesn't increase the fps They are going to try and machine another inner barrel to extend it.
