Vfc scar h feeding issue

[Long_Bong]

Hi,

I m running a VFC Shar H, stock, except for a Tanio Koba twist barrel and a new hop up rubber (purple prometheus),

I have a "strange" feeding issue, mags (modified PMAGS and the stock hi cap that came with it) feed bad (ie BB go out very slow or not at all) once I start shooting, but feeding is fix once the pressure from the mags is lower (less BB pushing).

First time I encouter a feeding issue related to the pushing pressure exerted by the mag (it feed well once feeding pressure is reduced).. Anyone found a way to some this issue?

Thanks!!!

Try a softer hopup rubber. I got a similar result when I tried heavier rubbers and concave spacers.

Guarder clear and and the stock nub seem to work best.

I don't agree with the guarder clear (only cuz i have had nothing but problems with the) but a softer hop maybe.

Also i have a H with pmags and here are a few things i have noticed when i was having problems

when you put the pmags in and its not aligned right the mag will press hard against the magwell feed nipple that puts bb's in to the hop up causing bb's to not flow nicely in to the hop up chamber you can tell that the hole looks like its getting flat. you will have to mod the little nipple and cut it down a bit to make sure the mag feeds perfectly in to the hop up nipple

Second is the screw in the mag well to hold the spacer on where the nozzle goes through it. check the alignment of this spacer if the screw that holds it i place is super tight it can throw off the feeding. (weird i know but it fixed my problems)

fist think you can try is deff change the hop up rubber.

This is true. That screw is long enough that when tightened, it contacts the nozzle which will disable it or limit from moving. That will certainly give feeding issue and loose some fps. I had to shave the screw a bit to shorten it.
