    Umarex Gauntlet Tune O-ring Kit
    $17.00

    Hajimoto Productions Tuning O-ring kit for the Gauntlet and Gauntlet 2

    Now includes my “NO RING” pellet probe seals as HP-1 rather than the typical high wear donut orings.

    I have put together the most common o-rings that fail during a tuning session. Most of the stock o-rings for the internals will gouge when the airgun is disassembled, this kit will allow you multiple attempts should any of the o-rings fail. Please note that the .30 caliber uses completely different internal o-rings than all previous Gauntlet Models including the .30 cal exclusive transfer port orings Which will be bagged as TP.

    Some of the NO-Ring seals have the leading edge precision ground.

    These tapered / precision ground types need to be installed as shown below

    (Images are of the .30 caliber NO RING)

    You get:

    • 2  of pellet probe NO-ring seals.
    • 2 sets of barrel o-rings.
    • 2 sets of tank block o-rings.
    • 2  of valve body o-rings.

    $18.50
    Umarex Gauntlet Regulator Shim Pak
    $18.50

    Hajimoto 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.

    Regulator Service or Pressure Change
    $45.00

    This is a service to repair, test, leak test, adjust or increase the output pressure of a Umarex Gauntlet 1 or 2, regulator to a customer’s requested output. The regulator will be tested and calibrated to within +/- 75 PSI. Parts such as Gauges, Burst discs, Bonnets, Pistons, Caps, or Regulator bodies are not included. If parts are determined to be required to repair the regulator, pricing will be determined, quoted, and will need to be paid prior to the return of the regulator.

    Please note that if you have a Taiwan-produced regulator, which is the regulator that is located at the top of the photo, there are very limited corrections that can be made to these units and you may end up needing a new regulator. Please use the notes area to provide the Generation and caliber of the rifle. Also, give as much detail as possible of the issue or the requested pressure output and so forth.

    Once the order is physically reviewed, you will receive a second notification with details associated with packaging and shipping the items in for service.

    When you place the order for the above-described service, you will receive an order processing notification. Shortly after that, you will receive a detailed notification with the shipping information for you to ship us your regulator or regulator and tank assembly.

    This service is not a hydro test of the tank/bottle and is focused only on the regulator’s functionality and visual inspection assemblies.

    Please note that this service is not associated with any manufacturer’s warranty, so please be sure to exhaust all warranty options prior to sending us your regulator for service as our working on the part voids any manufacturer-provided warranties.

    The single largest performance increase modification item for the Gauntlet. The Super Tune Kit allows complete power adjustment which opens all the possibilities of lower or higher foot-pounds (FPE) of energy for whatever the user desires. Do you need only 5FPE no problem back off the adjustment using a 5/64″ allen wrench and you are only delivering 5FPE and will realize over 200 shots on a stock bottle fill of 3000PSI!

    Want 27-30FPE for dropping that 20lb trash bandit, no problem, crank up the adjuster using a 5/64″ allen wrench and you instantly have the power necessary for either long range or high energy delivery on target. The use of a chronograph is required in order to know what the rate of travel is of the projectile and there is no better chronograph than the FX Pocket Radar V2. (Power examples given are the .22 caliber version Gauntlet 1) 

    For the Gauntlet 1 and Gauntlet 2. Be sure to select the proper generation as there is a difference and improperly selected kits are not returnable.

    Gauntlet O-ring service
    $95.00

    This service tears the entire air rifle down, cleans and inspects for part wear, and replaces all the o-rings in your Gauntlet. Whether the o-rings are leaking from age or wear, whether the rifle is actually leaking or not, all o-rings are replaced. The rifle undergoes an incoming inspection which captures the functional and physical condition of the air rifle. This information is presented in a report which must be reviewed and approved prior to any work can begin.
    The o- rings that are replaced are:

      • (2) Regulator to gun o-rings.
      • (1) Stock end cap o-ring.
      • (1) Stock air stripper o-ring.
      • (1) Barrel to shroud support collar at breach block o-ring.
      • (2) Bottle block to pressure tube o-rings.
      • (1) Valve body o-ring.
      • (2) Pellet probe o-rings.
      • (3) Barrel to breach block o-rings.

    The action is verified and lubricated prior to returning the rifle. The rifle undergoes a pressure test for 24 hours to guarantee there are no pressure losses.

    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.

    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.

DonnyFL Suppressors are sized so the first number is your PCP’s actual caliber and the second number is one size up. So if you owned a .22 caliber Gauntlet, the size you would select is .22/.25. If you had a .25 you would choose the .25/.30.

    If Your Gauntlet is:

    • .177 Get a .177/.22 Supressor
    • .22 Get a .22/.25 Supressor
    • .25 Get a .25/.30 Supressor

    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.

    22.5ci/370cc/.37L CE Certified CF Tank
    Shaves off 1/2 a pound of weight compared to the 4500psi stock aluminum tank.
    A complete regulator rebuild kit is included!

    Includes the New Hajimoto Pro V3 regulator with Stainless Steel rotational bonnet.
    Say goodbye to gauges and foster nipples not lining up with the openings in the stock.

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

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

    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.

    Range & Power Trend Service
    $310.00

    This is the service that is included with the Gauntlet 1 Platinum Package as well as the Gauntlet 2 Gold, Platinum, and Ultimate packages. The service is an add-on for lower airgun package offerings that run the rifle through a series of shooting exercises in order to capture and chart power generation and accuracy. This service produces the actual targets shot by your rifle at 25 and 50 yards on 2″ targets. The responses that you provide during the questionnaire are what we use during the final adjustment and execution phases.

    You will receive a detailed build sheet that captures every detail of what was performed on your air rifle. You will also receive a detailed data matrix and range result sheet which has the power generation matrix with different ammo weights, feet per second, foot-pounds of energy developed, and what the power adjuster was set to in order to develop those results.

    These data sheets become a quick reference for baseline performance data that you can always refer to in order to understand where your power adjuster should be in order to achieve the stated results.

    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.

    Please note that this combo will not fit a Gauntlet or Gauntlet 2 as the tank diameter is larger than the rifle’s tank shroud will allow. This combo is intended for builds that do away with the tank shroud or to be used on other PCP’s that allow for a typical paintball regulator installation.

    We completely tune your supplied Gauntlet 1 or 2 which includes everything listed in the section below.

    The service includes a very detailed and time-consuming incoming inspection report that includes photos and other relevant information that detail the condition of the airgun and all of its pieces and parts. This report is provided to you and you must be reviewed and authorized in order for the work to continue.

    • Check out.

    Shortly after the order is received,  you will receive an email notification containing shipping information that will include labeling and packaging requirements.

    To better understand how the Gauntlet is transformed from a static you get what you get type of airgun, into an adjustable power and tunable PCP, take a look at this video that demonstrates how the power adjuster works if you should want to increase or decrease the power output for any given ammunition in order to get it to fly at the best rate of travel for that particular ammunition.
    HOW TO ADJUST POWER WITH STK

    We will build your order based on the information provided from the questionnaire as well as any specific requests, and before the airgun ships, any credits or additional charges will be settled.
