I just picked up a VFC 416C GBB and I wonder about the mags for it, I can never tell when it is full of gas. Is it the mags or is there a differnt type of fill vaule that will blow back when the mag is full?
When i installed my fet, i had to open the mechbx to clean out the switch due to some of the plastic sticking to each other. I sidder my own wires to the switch and may over heated them a bit. This caused some sticking for me.
