Requires minor forestock modification.
The regulator thread is 5/8-18UNF (Bottle Thread) and Typical Paintball Threads of .825-14 NGO (PCP Thread).
Please note the Flex regulator can be used with any Air, Co2, or Nitrogen driven air gun not just the Gauntlet, providing it has the correct threading.
The Ninja Flex regulator is available in any 900 psi spread to a maximum of 3100 psi output. For the Gauntlet, select the proper configuration.
If you select the Custom Configuration, you will need to use the NOTES above to communicate what you want the maximum output to be. Please note that the highest output the Flex Regulator can be configured for is 3100 PSI, but we can build it to any number below that. Example, a user wants the maximum output of their Flex regulator to be 2800, we will build the regulator so that the adjustable range of that build is 1800 to 2800PSI.How to read the below configurations

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.

Remember to always order your suppressor one size larger for shrouded barrel PCP’s.
If you have a .22 caliber shrouded barrel PCP, you’ll want to order a .25 caliber suppressor.
The .177/.22 is for shrouded barrel .177 or direct barrel threaded PCP’s in .22.
The .22/.25 is for shrouded barrel .22 or direct barrel threaded PCP’s in .25.
The .25/.30 is for shrouded barrel .25 or direct barrel threaded PCP’s in .30. The exception to this rule is the Gauntlet .30 is shrouded but because of the unique end cap, marries the barrel and shroud at the end.The Tanto, Tatsu, FX, or Sumo are not recommended for the Gauntlet .30 caliber because of the relatively small internal volume of these suppressors and the elevated operating pressures of the G30. We recommend the Ronin be used on all of our G30 Builds.

HP Strip Stak Pak for Avenger
$47.00Select optionsUPDATE: The newer avengers have a screw-on barrel shroud and an end cap that is a two-piece unscrewable but the STP still fits and works without an issue. unscrew the shroud rather than the little screw shown in the video and simply unscrew the baffle washer array off the end cap and you are good to go.
Strip Stak Pak for the Avenger
A six piece kit that includes an efficient multiport air stripper that strips and channels air away from the pellet to allow for a more stable and less turbulent pellet launch from the muzzle. The kit also provides baffle chambers to help remove both noise and turbulence in the air stream. The end result is a more laminar air stream which reduces projectile instability and as a secondary benefit, reduces the report of the rifle. This kit is 100% compatible with the stock end cap or the DonnyFL A50 adapter.
Air Stripper comes with o-ring and silicone grease for installation. The installation video for the Umarex Origin Strip Stak Pak is exactly the same so you can follow the installation video below.Replacement Air Stripper 0-ring is 14mm x 1.5mm
