The Gauntlet 1 will need to have its tank shroud inside diameter increased slightly to allow the foregrip/tank cover to side over this carbon fiber tank or simply remove the tank shroud.

Introducing a Hajimoto Productions Exclusive offering!
18ci/295cc/.29L CE Certified CF Tank

Fits the Gauntlet 2 without any modifications.

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. An 18.3ci carbon fiber 4500PSI cylinder with externally adjustable Ninja Flex Reg for your Umarex Gauntlet! The massive volume of air afforded you is mind-blowing.

The diameter of the tank is 54-55mm across so a modification to the forearm is required if you desire to continue to use the Gauntlets tank shroud. 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.

Gauntlet Bottle Shroud Mod

Please see the examples provided in the accompanying photos.

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. Please be careful if you have accessories on any of the MLok openings as the screws or MLok fasteners may scratch the tank when the shroud is slid forward or back.

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!.

The cylinder’s outside dimension is slightly larger than the stock aluminum tank so my standard HP Barrel Band does not fit. You will need to use the HP Barrel Band CFT version
```
Regulator is Made in the USA!
The Power Flex Combo is set to either of the two Gauntlet configurations.
Simply select the proper configuration.

500cc CF Tank with Adjustable Reg
Flex Reg RTI Version & Tank
$310.00 – $350.00

Flex Reg designed and configured specifically for RTI PCP’S such as Prophet, Priest, & Priest 2
This Flex Reg comes paired with a brand-new Carbon fiber 4500PSI tank. The regulator is externally adjustable and has an effective adjustable range of 900PSI (62bar).

Using the slider you select what the maximum output will be and because the regulator has the ability to adjust, you can reduce that maximum output pressure down as much as 900PSI (62bar). You can of course set the pressure anywhere along that 900PSI (62bar) range to suit your tuning requirements. The regulator will not have a pin or ball seal in the bonnet. The tank cannot be removed while under pressure and must be degassed.

Because of practical limitations, regulator max output will be +/- 50PSI (3.5bar) within the requested maximum output.

Comes with a spanner wrench for adjusting the output on the fly.

** This regulator is 5/8″-18UNF threaded and will not fit M18 threaded bottles. This configured Reg is not sold separately.

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.

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.
