VFC AK74 Npas

At the risk of sounding very stupid (Nothing unusual!)

Is this shiny silver adjustable thing the NPAS adjuster?

My fps is 225 roughly on a 0.25g bb which seems a little low ?

No, that's a restrictor disc, it's not beneficial and can be removed by screwing it out. Leaving it in causes backpressure against the rocket valve when closing, which hampers blowback slightly and can introduce inconsistency in FPS.

Inside there may still be an npas, mine had the restrictor and npas as well

What would I be looking for in the nozzle to see if it is an NPAS?

No problem, the general go-to for vfc npas is cl project but vfc does their own, I'm not sure how readily available they are however

cl project

CL Project was on fire support but out of stock so set up an email reminder. Gonna refit the restrictor so I can field it this weekend though

Where did you get your rifle as all the official Uk ones had npas installed rather than a restrictor

Oh i see, they are grey imports from Asia so that makes sense
