The all new Ninja Carbon Fiber Superlite Tank (90/4500) includes a Pro V2 paintball style high-PSI regulator for use in airsoft HPA tapped guns. The 90/4500 is the largest super light air tank made! The SL Super Light tanks weigh much less than other air tanks on the market. The tank includes a PRO V2 'paintball style' output regulator pushing out around 800 PSI. This will work with all Wolverine Storm, Ninja LPR, and non-SLP regulator line systems. Will also work perfectly with the Tippmann gun system.These are very lightweight, yet huge air capacity tanks. The best money can buy!
