    Ninja High Pressure Metric M18 Custom Output
    $154.95 – $155.00

    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.

    Take advantage of a quality regulator for your high pressure application.

    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.

    Remember it is recommended that you 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 which is shrouded but because of the unique end cap, marries the barrel and shroud at the end.

    If you have a .22 caliber shrouded barrel PCP, you’ll want to order a .25 caliber suppressor.

    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.

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.

    FX Pocket Chronograph v2

    The original FX Chronograph changed airguns by providing the
    most important tool a modern shooter must have, in a compact, portable unit. Now FX Airguns is pleased to introduce the even smaller and improved FX Pocket Chronograph v2.

    The v2 Pocket Chronograph is more pocket sized than ever at just
    under the size of a 2” cube. It now has an internal battery that is recharged through an included USB-C cord. Multiple mounts are also included that allow the shooter to attach the chronograph to their rifle in multiple ways.

    The chronograph itself can be used for more than just airguns. Any
    projectile traveling under 1250 FPS can be accurately measured. This includes subsonic rifles, pistols, CO2 air rifles, paintball, and more. Since the unit uses radar technology, the Pocket Chronograph can be used in any weather condition without external accessories.

    The setup is the same as the older version. To learn how to use it, follow the link here to watch the tutorial video.

    Power Flex Combo 18.3ci Carbon Fiber 4500PSI
    Original price was: $339.00.Current price is: $295.00.

    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.

  • Flex Reg RTI Version & Tank
    $310.00 – $350.00

    500cc CF Tank with Adjustable Reg

    Flex Reg RTI Version & Tank
    $310.00 – $350.00

    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.

    Introducing a Hajimoto Productions Exclusive offer!

    22.5ci/370cc/.37L CE Certified CF Tank
    Newly redesigned unit
    Now has a high pressure and low pressure burst discs!

    Installs on the Gauntlet 2 with minor tank shroud modifications, forearm slides right over the carbon fiber cylinder.  Installation video at the bottom of the page.

    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 included a 22.5ci carbon fiber 4500PSI cylinder with externally adjustable Ninja Flex Reg for your custom build including the Umarex Gauntlet 1 or Gauntlet 2! The massive volume of air in these 22.5ci tanks is mind-blowing!

    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.

    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.

    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. See photo below

    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 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.
