If you are looking to add an externally adjustable reg to your Gauntlet 2, take a look at swapping your current fixed reg to the Flex reg found HERE
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.

100% get this for your Gauntlet .25!
My Gauntlet .25 has a larger 22 cu. in. bottle and the reg turned up to 2100 psi.
I installed this kit and had an issue. No fault of Hajimoto Productions. 100% my own doing. I emailed him and sent photos. He had the fix right away.
I sent 3 mags across the chronograph after that with 25.4gr JSB Exact Kings at 895 fps or 45 ft. lbs. the spread was a whopping grand total of 5 fps!! Insane! You talk about consistency! WOW!
If you get this kit be sure to order the O-Rink kit. I can almost guarantee you will “scalp” some O-Rings in the process. Just the this gun was made.
It is really nice having the option of adjustability along with a much more efficient valve setup on your Gauntlet.
Customer service Can’t be beat either! Hajimoto is a real awesome Dude!

Wow! I had no idea what this upgrade would do for me.
I was a little disappointed after making a few changes but everything came together I started playing around with the hammer preload adjuster.
I installed a 22 cu in bottle with a new regulator set at 2200, new rings, a high travel valve stop, and the Super Tune Kit in my Gauntlet 1 .25 cal. I started out getting around 920 fps with 33.95 JSB’s. HOWEVER, I was only getting about eight shots before it started falling off and after about 16 shots my overall pressure went below 2000 psi. It was hitting hard and pretty accurately but I got tired of filling it up. (I actually forgot about the power adjuster) I took the regulator down to 2000 and started playing around with the power adjuster. Eventually, I landed on about 805 fps and was very accurate. The most important thing that I stumbled across is that the power adjuster really helped me increase my shot count. I was getting about 25+ – 805 fps shots. Even after it dropped off my poi was still pretty good.
Also! The gun is so smooth, it was kicking quite a bit before but now it’s perfect. I was hitting a small 1/2″ socket at 50 meters and killing my paper. It feels so good, this must be the sweet spot for my gun, everything just came together because now I could simply adjust the hammer. I didn’t know too much about tuning and harmonics so I watched a bunch if vids, now I have a little better understanding as to what I was doing.
THIS KIT IS A GAME CHANGER! MANY MORE CONTROLLED SHOTS AND VERY SMOOTH/QUIET!!!!!!
