Direct replacement with no modifications required for the Umarex Gauntlet 2 & G30/G30SL!
18ci/295cc/.29L 4500 PSI Carbon Fiber Bottle
Hajimoto is bringing sexy back! Doesn’t that carbon fiber look awesome on there!
Includes Ninja’s HP regulator.
The CF Tank is CE Certified made to ISO 11119-3 standard. They have seamless aluminum alloy 6061 liner wound with high strength Japan-imported carbon fiber and glass fiber reinforced plastic full composite layers and subjected to an autofrettage pressure. This 4500 PSI carbon fiber bottle is 18ci and is absolutely gorgeous on the Gauntlet 1 or Gauntlet 2.
The Gauntlet 1 will need to increase its tank shroud inside diameter to allow the foregrip/tank cover to side over this carbon fiber tank.

Flex reg and 30ci/500cc/.5L CE Certified CF Tank
Please note that this combo will not fit a Gauntlet or Gauntlet 2 as the tank diameter is larger than the rifle’s tank shroud will allow. This combo is intended for builds that do away with the tank shroud or to be used on other PCP’s that allow for a typical paintball regulator installation.
