Microbore 4500PSI Extension
Flex reg and 22.5ci/370cc/.37L CE Certified CF Tank
Introducing a Hajimoto Productions Exclusive offer!
22.5ci/370cc/.37L CE Certified CF Tank (Available in matte or glossy finish)
Newly redesigned unit
Now has a high pressure and low pressure burst discs!

Installs on the Gauntlet 2 with minor tank shroud modifications, forearm slides right over the carbon fiber cylinder. Installation video at the bottom of the page.



The CF Tank is CE Certified and 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 included a 22.5ci carbon fiber 4500PSI cylinder with externally adjustable Ninja Flex Reg for your custom build including the Umarex Gauntlet 1 or Gauntlet 2! The massive volume of air in these 22.5ci tanks 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.
Please be careful if you have accessories on any of the M-Lok openings as the screws or MLok fasteners may protrude into the tank area and scratch the tank when the shroud is slid forward or back. We recommend that if you have any MLok accessories installed, you remove them when sliding the shroud on or off. We also recommend covering the brass inserts in the tank shroud with cloth tape to protect your carbon fiber finish.
The Gauntlet 2 forearm slides right over without any issue. Only one access hole needs to be drilled so the fill port is accessible at the bottom. See photo below

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 regulator 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 +/- 75PSI to the requested output.
A quality water, oil and odor filter system designed to protect your PCP’s! Consider selecting the combinations that come with the extra-length fill whip so you can stand your filter up and down and still have plenty of slack to connect to your PCP.
Whether you are using a hand pump or a personal compressor it is vitally important that only clean dry air be introduced in your air reservoir.
Made from high-quality aircraft aluminum and is rated for safe use.
Don’t make the mistake of not drying your air as it will destroy regulators as well as your aluminum pressure vessels.
Available with a 47″ high-quality stainless steel fitting hose to allow for convenient filling of your PCP.
0.5L/500cc CE Certified CF Tank (M18)
