Installs on the Gauntlet with minor tank shroud modifications. (The Gauntlet 2 is shown to give an idea of what modification needs to happen and that is simply a hole drilled in the bottom of the plastic tank shroud for the fill nipple.

A 22ci aluminum 3000PSI cylinder with externally adjustable Ninja Flex Reg for your Umarex Gauntlet1! The volume of air in these 22ci tanks over the 13ci is mind-blowing!
The diameter of the tank is 54-55mm across so a modification to the forearm is required on a Gauntlet 1. I do offer a tank shroud modification service for Gauntlet 1 owners that can be added to a build or provided as a mail-in service.
The Gauntlet 2 forearm slide right over without any issue. Only one access hole needs to be drilled so the fill port is accessible at the bottom.
Consider picking up our extended foster fill adapter to make coupling and filling a breeze.
The Power Flex Combo allows the user to externally adjust the regulator output pressure on the fly with an adjustment range of 800PSI!
When installing the Flex 22 on the Umarex Gauntlet. Tighten the degassed tank and regulator assembly fully to the rifle, then back it off until the fill port is on the bottom and the gauges are left and right. Now fill the bottle with air and all will tighten up solid. Proper alignment will be achieved before the 360° maximum rotation limit is realized.
Comes with a dedicated Spanner Wrench for power adjustment. MADE IN THE USA!
Because of practical limitations, regulator output will be +/- 50PSI (3.5bar) within the requested output.
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.
