Umarex 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.

This is a 22.5ci / 370cc carbon fiber 4500psi max fill cylinder.
The diameter of the tank is 54-55mm across so a modification to the forearm is required on a Gauntlet 1. I 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.

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
All custom built pressure units will have a +/- 75 psi tolerance.

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