VFC 416C GBB Mags

[wilekcmc]

I just bought my first GBB and the mag is what i am not sure of. Most of my pistols are gas but the fill value always blow back gas when filled.

With the VFC 416C GBB I just picked up, i can never tell when the mag is full. Is there a different fill value or some way to tell when the mag is full?

Thanks

Not all GBB mags do this. I have pistol mags that dont. From full empty hold the gas can and just count slowly to 5. That should be enough to fill it.

While you are filling it you will hear the gas is going through the fill valve into the mag. When the sound stops the mag is full.
