Ninja Paintball is beginning to produce these with a polished brass bonnet. We will be forced to only offer the polished brass version once all the black steel bonnets are gone.

We do include the ball/pin and spring should you happen to have a thin pin depression system capable of actually opening the valve. The only function of this pin/ball is to allow the tank to retain air if it is off of the PCP. This is a paintball thing and should not be used in in HPA.

You should never try to unscrew a high-pressure output paintball-style regulator while it is under pressure. You will destroy the threads as they are not designed to be threaded on and off under load. Degas and then remove the regulator and bottle. Read more in the following article https://hajimotoproductions.com/index.php/2024/11/11/regulator-thread-damage/

The ball and spring are provided but removed from the regulator.

Installs on the Gauntlet with minor tank shroud modifications.

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.

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.

  Installs on the Gauntlet 2 with minor tank shroud modifications, forearm 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.
