Austeyr Posted April 11 Posted April 11 (edited) 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 ? Edited April 11 by Austeyr
Hobbnob Posted April 11 Posted April 11 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

Hobbnob Posted April 11 Posted April 11 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 Austeyr 1
