Otaku's Airsoft How to: VFC's NPAS system

I went on a bit of a tangent. At least it will be helpful. I hope...
Short answer is at 8:55

Thank you much, this has been very informative for a person who has just purchased his first gbbr (VFC 733). At the end of the video you mention that the NPAS can be adjusted by sticking an allen key through the front of the nozzle and then twisting the screw. This sounds conveniet because I don’t feel too sure about deassembling the gun further. Two questions however. 1) To i n c r e a s e the fps you turn the screw anticlockwise, right? 2) If you twist the screw too much can it fall out completely?

Weird thing is that they didnt put this into the VFC MP7 that gets exported to Germany here, even though its the same part on all VFCs. You can just order the part and retrofit it. Honestly, every single GBB on the market should come with an NPAS at this point. A single grub screw through a plastic valve cant be that hard or expensive...

Hey bro thx for making this vid I appreciate it.

[@MA15CHmellow]

You sir are a hero.🫡

[@keijomattinen5447]

I have the VFC M733. Can you say how much more (if any) fps you can get by putting a NPAS to the stock gun?

[@OtakuGekko]

It depends™️ on what you plan on setting the NPAS on, mine is set to max on my 417 and it gets 2.6J~ with .32s

[@warhead_beast7661]

The screws are really hard to get out they sit really tight, any tips?

[@tarrlevente1]

Hi! Is the 416/M4 NPAS valve the same as the SR25/417?

[@OtakuGekko]

Yes, the NPAS valve is a standard component across a good portion of the VFC AR systems

Hex key into nozzle and see if it catches and turns. So, which directions (clockwise & anti-clockwise) increase or decrease power? Thanks

[@mrpuffels5450]

he says in the video bruh

[@Effdddgr]

@@mrpuffels5450no he doesn’t instead of saying clock wise our counter he just fumbles around with leaving you more confused

[@bobybot9320]

how do you get the "retaining spring nut" back into its original place? it's extremely hard toget it back into position, i still haven't found a way Also how did you get the pins inside the nozzle to budge? mine are hard stuck, and i wouldn't want to destroy my whole nozzle through brute force

[@OtakuGekko]

For your first question, trial and error. I agree its a major pain in the ass to realign. As for your second question, using a alan key and a very big hammer. The pins holding the nozzle in place are require a bit of force to remove

Hello I have a vfc MP7 navy with stock npas . Over the winter it shot 330 fps but yesterday in around 77 degree weather it shot hot. I tried to adjust the npas at the field but the set screw for the npas came out .. I put it back in but now My bbs are not feeding properly . Idk if I have it so low that no air is going to the bb or I broke something with the hop up or nozzle When I leave the screw out it shows 290fps Help

[@OtakuGekko]

Its probably a mix of both, my first assumption is when you over adjusted as I failed to mention that you don’t need to crank it that much to change the FPS.

[@christianherrero8053]

@@OtakuGekko I also forgot to mention that I put the screw back in through the nozzle .. I never actually opened up the nozzle and tried to reconstruct it . Just confused as to why the bbs aren’t getting any air

[@OtakuGekko]

I’d recommend taking apart the bolt to see but if you aren’t comfortable doing so, take it to a airsoft tech

[@Foursquares27]

What size Allen key are you using? I can’t seem to find one that works. ( I know for sure I have an NPAS in my Scar)

[@navidmossavati3558]

Have you found a solution yet? Just ran into the same issue with my scar lol

[@waterstarrunner]

@@navidmossavati3558 1.5mm on the HK417. I think the valve itself on the SCAR is exactly the same.

[@OtakuGekko]

@waterstarrunner its the same across a wide variety of VFC products

[@DirtyGhettoKook]

Can confirm it’s a 1.5mm for the APFG Rattler, essentially VFC rebranded.
