Installation of our Sidelever on G2 or G1
Gauntlet Sidelever Install
Original price was: $220.00.Current price is: $195.00.

This service is for the installation of our sidelever cocking system installed in your action. The Sidelever is no longer being offered for .30 caliber variants.

Our side lever system eliminates one of the main gripes folks have with the Umarex Gauntlet and that is COCKING EFFORT!

There is no comparison in cocking effort when you apply the mechanical advantage a sidelever gives you. The installation is a non-destructive installation and can be reversed without any compromise to the airgun’s action or stock.

The sidelever system is a CNC milled 6061 Aluminum part which is hard anodized for a great match to the existing Gauntlet finish. The cocking vertical handle is an additive manufactured carbon fiber & ABS part that can be swapped out by you if you wanted to use a custom handle from wood or other material.

Our sidelever cocking system does require that you hold the handle back to swap mags but there is no need to hold back if you single load using the single shot tray.

One of the most common questions we get is “Can I just buy the parts and install them myself?” and the short answer is, no you cannot. For the reasons why, please read the ARTICLE we published in our blog in February 2023 on this topic.

370cc/.37L CE 5/8″ Threaded
370cc/.37L/22.5ci Carbon Fiber 4500PSI Tank
$220.00
Introducing a Hajimoto Productions Exclusive offer!
- Shaves almost a full pound of weight off your G2 or G30.
- 22.5ci/370cc/.37L CE Certified CF Tank.
- 5/8”-18UNF Threaded so Stock Gauntlet Regulators will thread directly to this bottle.
  
  Installs on the Gauntlet 2 with minor tank shroud modifications, and the bottle shroud slides right over the carbon fiber cylinder.
The CF Tank is CE Certified and made to ISO 11119-3 standard. They have seamless aluminum alloy 6061 liner wound with high strength Japan-imported carbon fiber and glass fiber reinforced plastic full composite layers and subjected to an autofrettage pressure. 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.

Introducing a Hajimoto Productions Exclusive offering!
18ci/295cc/.29L CE Certified CF Tank

Fits the Gauntlet 2 without any modifications.

The CF Tank is CE Certified made to ISO 11119-3 standard. They have seamless aluminum alloy 6061 liner wound with high strength Japan-imported carbon fiber and glass fiber reinforced plastic full composite layers and subjected to an autofrettage pressure. An 18.3ci carbon fiber 4500PSI cylinder with externally adjustable Ninja Flex Reg for your Umarex Gauntlet! The massive volume of air afforded you is mind-blowing.

The diameter of the tank is 54-55mm across so a modification to the forearm is required if you desire to continue to use the Gauntlets tank shroud. 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.

Gauntlet Bottle Shroud Mod

Please see the examples provided in the accompanying photos.

The Gauntlet 2 forearm slides right over without any issue. Only one access hole needs to be drilled so the fill port is accessible at the bottom. Please be careful if you have accessories on any of the MLok openings as the screws or MLok fasteners may scratch the tank when the shroud is slid forward or back.

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!.

The cylinder’s outside dimension is slightly larger than the stock aluminum tank so my standard HP Barrel Band does not fit. You will need to use the HP Barrel Band CFT version
```
Regulator is Made in the USA!
The Power Flex Combo is set to either of the two Gauntlet configurations.
Simply select the proper configuration.

Power Flex Combo Configuration For .177/.22 Cal
Flex Reg set to 700 to 1500PSI
```
```
Power Flex Combo Configuration For .25 Cal
Flex Reg set to 1600 to 2400PSI
```
```
DO NOT USE Power Flex Combo Configuration For .25 CONFIG on .177 or .22
they are not capable of handling the pressures.
Because of practical limitations, regulator output will be +/- 50PSI (3.5bar) within the requested output.

This 4500 PSI carbon fiber bottle is 22.5ci and is gorgeous on the Gauntlet series of PCP.

The Gauntlet 1 will need the inside diameter of the tank shroud increased slightly to allow the foregrip/tank cover to slide over this carbon fiber tank, or simply remove the tank shroud.

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 regulator 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 +/- 75PSI to the requested output.
