For G1 G2 & G30 Variants
Hajimoto Productions Tuning O-ring kit for the Gauntlet and Gauntlet 2
Now includes two of my “NO RING” pellet probe seals as HP-1 rather than the typical high wear donut orings.
I have put together the most common o-rings that fail during a tuning session. Most of the stock o-rings for the internals will gouge when the airgun is disassembled, this kit will allow you multiple attempts should any of the o-rings fail. Please note that the .30 caliber uses completely different internal o-rings than all previous Gauntlet Models including the .30 cal exclusive transfer port orings Which will be bagged as TP.
Some of the NO-Ring seals have the leading edge precision ground.

These tapered / precision ground types need to be installed as shown below
(Images are of the .30 caliber NO RING)
You get:
Fits the G1, G2/G2SL or G30/G30SL
Full-fledged 2-stage trigger for the Umarex Gauntlet 1, 2, G30, bolt or sidelever variants. This trigger is a direct replacement for the single-stage trigger that ships with the Umarex Gauntlet. This trigger is a straightforward install that will increase the accuracy of your shooting due to a more predictable and consistent breakpoint.
Please see the installation video below for more details.
Super Tune Kit Users
You must use the stock trigger return spring with the two-stage trigger as the trigger spring that comes with the Super Tune Kit is too light to be effective with the two-stage trigger.

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.
