What I have lying around is a GOVNAIR system tahat came with an old automag I bought.
It has never been tested because I have no way to fill it. Everything looks ok, though I cannot guarantee anything, so I take no responsibility for it.
It comes without the microline fittings. I heard that the ols fill nipple can be replaced with one of the newer ones.
Price: 20bux?
This item will be shipped from Poland, so be advised that shipping will cost circa 50$.
AGAIN: I WILL NOT TAKE ANY RESPONSIBILITY IF SOMETHING HAPPENS TO YOU. SOLD AS IS.
