I got a 4500psi HPA carbon fiber tank, just rehydroed last year with a MaxFlo micro reg on it.
I also have a 3000psi steel tank that is in hydro, but the fill nipped leaks. Easy fix.
And I have a 3000psi steel tank that works great, just needs to be rehydroed.
$120 shipped takes all 3.
I'll part out the carbon fiber for $90 shipped and each of the steel tanks for $20 shipped each.
