I don't have an NPAS, but I have a general question regarding the floating valve/bulb inside the nozzle. I sanded down 2 teeth in the nozzle which hold the floating bulb in place (WE/WELL AK74 GBBR). Now the air inlet ratio is far in favor of the barrel instead of the bolt. I did this to maximize FPS. There is still some little space left for the gas to enter the rear of the nozzle for the blowback action to occur. But now I am getting cycling problems. The gun fires ok first 15 rounds then starts shooting bursts on semi. Having taken the lid off, I can see that in these cases the bolt doesn't travel all the way back to set the hammer, but rather bounces against the hammer several times, causing the bursts. So can the floating valve inlet ratio cause cycling issues?
Yes. It will cause cyclic issues. In yo case, the gas output is consistent. However, your mod to the bulb makes most of the gas escape from the barrel while propelling the BBs, and not the remaining gas is not strong enough to push the bolt all the way back to reset the hammer

Hello, what barrel should I use for this piston? I care about range and precision
This won't work in the WE kac pdw without some mods and a tighter oring
Does this work with the open bolt we pdw

How can I buy it.bro.and. how much
I think evike has some of the npas stuff. Not sure if it’s the exact same. They advertise the full metal on the evike website
Emperionstore
what does NPAS stand for?
I think it’s Nozzle Pressure Adjustment System or something along those lines
