My solution for my TalonP:https://www.ebay.com/itm/3000-PSI-Aluminum-Tank-Air-Cyclinder-Bottle-For-Paintball-PCP-0-38L-5-8-18UNF/132341499335?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649
Yes 380cc but a lot more than the original tank.I have several Condor Tanks with various valves as well so I switch depending on whether I want light weight or more shots.
Anyone happen to know where I might find a M18x1.5 male to 5/8-18 female adapter. I'd like to put a larger tank on a TalonP. PCP Tunes has one for $50. Seemed pretty expensive but I was going to buy it until they added another $31 for shipping. Just can't see $81 for one.
