Kriss vector npas
 

hi guys ive got a kwa kriss vector and i just install a ra-tech evo 2 hop-up/inner barel set and a mp7 kwa / ksc npas and i want to know if anybody did this mods ans can tell what kind of fps they have with a closed and open npas ?

I can tell you that when my NPAS was fully closed I got 1-15 FPS,

ok that weird its not supposed to be higher than that because normally when the npas is fully closed is suppose to be at max fps or maybe i mistake myself ?

i can tell you guys right now if you want to change the valve to play in cqb the ratech npas for a mp7 not a good idea . ive chrony my gun tonigh ive got 260 fps with the npas at is maxx fps output so if you want to save money go for a danger werx valve that will give you around 315-325 fps with .20
