$18.50Umarex Gauntlet Regulator Shim Pak
$18.50Select optionsHajimoto Productions Regulator Shim Kit For Umarex Gauntlet
I have put together a very easy and complete stainless steel shim kit so you can adjust your Gauntlets Regulator output. The shims that I have included give you a wide range of adjustability to mix and match different thicknesses to get the regulator to output exactly what you want. The shim kit comes with easy to follow instructions which guide you through the process as to what shims you need to add to typically achieve my recommendations for each Gauntlet Caliber.
The shim kit contains:
- 2 – #5 Shims.
- 1 – #3 Shim.
- 2 – #2 Shims.
(Two #2’s = One #4 | Two #5’s = One #10 | One #5 + One #3 = One #8, and so on)
To take a stock G1 .177/.22 from the stock 1100-1050PSI to my recommended 1350-1400PSI you would add two (2) #5 shims (10).
To take a stock G1 .25 from the stock 1900-1950PSI to my recommended 2100-2200PSI you would add one (1) #3 shim (3).
The included two #2 shims are for minor adjustments if you have a finicky regulator.DETAILED LESSON/EXAMPLE:
Let’s say your .22 Gauntlets regulator only puts out 1300PSI after installing the two #5’s when it should be 1350 to 1400PSI, you would add one #2 for a total of 12 to help get it there. If after the addition of the one #2, you’re still 50psi short so you would pull out the #2 and use the #3 for a total of 13.Always use a regulator output tester to confirm the output pressure of your regulator. It is the only safe and sure way to properly adjust the pressure of your regulator.
You have to fill and purge so the Belleville washers settle into the new preload. Be sure to slow fill your bottle the first time only to 500PSI and then purge it, fill slowly a second time to 1000, and then purge fill the final time slowly and watch to be sure the reg has settled and does not exceed your target pressure. If it does exceed your target pressure, stop filling, purge and shim less.
If you rapid fill, there is a good chance you will pop your burst disc.

The barrel band is designed to live at the end of the cylinder as shown and has a section of Picatinny rail on the bottom to allow for the attaching of a bipod, flashlight, camera, or laser pointer. The Picatinny rail is not designed to support the entire air rifle in a clamp or tripod used in standing rests.
This Barrel band is specifically designed for a Umarex Notos with our HubenPower Dream TK installed with our 300cc or 360cc carbon fiber bottle with a Hajimoto modified barrel installed.

$310.00 – $350.00500cc CF Tank with Adjustable Reg
Flex Reg RTI Version & Tank
$310.00 – $350.00Select options
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.

A 13ci aluminum 3000PSI cylinder with externally adjustable Ninja Flex Reg with typical G1/2-14 threads connects to your Umarex Gauntlet 1 or Gauntlet 2 without any modifications!
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 13 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.
