Range & Power Trend Service
$310.00

This is the service that is included with the Gauntlet 1 Platinum Package as well as the Gauntlet 2 Gold, Platinum, and Ultimate packages. The service is an add-on for lower airgun package offerings that run the rifle through a series of shooting exercises in order to capture and chart power generation and accuracy. This service produces the actual targets shot by your rifle at 25 and 50 yards on 2″ targets. The responses that you provide during the questionnaire are what we use during the final adjustment and execution phases.

You will receive a detailed build sheet that captures every detail of what was performed on your air rifle. You will also receive a detailed data matrix and range result sheet which has the power generation matrix with different ammo weights, feet per second, foot-pounds of energy developed, and what the power adjuster was set to in order to develop those results.

These data sheets become a quick reference for baseline performance data that you can always refer to in order to understand where your power adjuster should be in order to achieve the stated results.

Introducing a Hajimoto Productions Exclusive offer!

22.5ci/370cc/.37L CE Certified CF Tank
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.

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.

Please be advised that if you use the 370 cc bottle and want to continue to use your stuck bottle shroud, be sure to remove any MSLOT accessories off the tank shroud before sliding it over your new carbon fiber tank as it will scratch it.

Watch my video below that goes over how to modify the brass inserts so they don’t scratch the tank also.

We build the regulator to any custom output pressure in 100 PSI increments from 1100PSI to 3100PSI
