Lower Velocity on KWA MP7

[FletchMadness]

So Im almost certain of buying this gun, however, the velocity is far too high for my CQB field. My limits are 320 FPS
I heard there is a lower bolt assembly, but that only reduces it by 50 FPS and thats just not enough.
I could just use duster, but that is hard to find, and expensive. any thought or suggestion? like a new piston or something?

Ra-tech NPAS

A few of our friends bought one, and all three guns shot over 420 FPS. They used an Reducer valve (as suggested above), and it worked. I don't know however how low it got. Duster gas is not hard to find at all. It's computer cleaner, and should be able to be acquired from any relatable store. Also, you'll need the duster can adapter. You can order them online, for about $6.00.

I have a duster adapter, and duster gas isnt hard to find, its the HFC 134 a duster that can be difficult to acquire.

the proper duster gas that doesn't eat seals/rubber is what's needed... it's getting harder to find these days, but it's still out there. I'd try the npas first.

[McCrea]

I can go as low as 250 fps with the npas and as high as 440 fps...

The only ones I can find say they are made for SCAR or M4s. do you think these will work?

It will not. This is the one you are looking for:

will that work in the kwa m11?

There's also the rocketwerx valve or compete low power bolt assembly. Npas or rocketwerx valve is probably best bang for the buck.

I have the dangerwerx valve. Works like a charm.
