Anyone have any suggestions. All three of my kwa vector gas mags seems to be leaking on every shot I take. Now I’ve had to change the cylinder to the carbon fiver printed on due to my original one breaking so unsure if it’s that, that is causing the leak if it’s not sealing correctly to the top of the mag or if it’s the top rubber on the mag that is causing the leak. I’ve just recently bought all new O rings for all of my mags and changed then ruling out the O rings but I’m now at a lose and if I can’t solve it, I’ll probably just have to retire my vector.
