I have a ninja 50/4500 grey tank born on March of 2012 so it has lots of life left. There are some scratches on the reg and one small nick on the top of the bottle near the reg. the reg was on another tank and works perfectly it just took a bit of a beating while getting it off. It does work perfectly and is outputting around 550psi currently. I'm asking 110 pp'd and shipped because of the scratches and I feel that is a fair price considering the life left on the tank and i'm including the ninja tank cover. So overall a pretty good deal.
No trades just cash
$110.00 PP'd and shipped
Those are not scratches or chips at the top of the black it's imperfections in the black when wrapped.
