Install Super Tune Kit

$70.00

Please note that these are services to your rifle and not just the parts. If your looking for parts only head to the PRODUCTS section of the website.

The service of installing the Super Tune Kit does not include shipping. Return shipping will be calculated and added at check out. Shipping cost will be based on a complete rifle sent to Hajimoto Productions in the original box and packing materials. Stock modification is part of the STK install which is why you need to send the entire rifle to us not just the action. If the rifle is received in something heavier than the typical 14lbs, additional shipping costs will need to be paid prior to the rifle being shipped back to the customer.

Description

Please remember you have to purchase the STK, this is only the Labor to install it. Be sure to add the STK to your cart as well.

Installation of the Super Tune Kit in your Umarex Gauntlet. Price does not include shipping or parts and represents shop time or labor only.

The rifle will be disassembled, and all STK parts will be installed, STK poppet, STK Hammer Spring, STK Power Adjuster. The STK trigger spring and trigger adjustment can be added as an option but are not included in the base STK Installation price as it requires trigger tuning which is a listed service option found HERE.

Also this does not include the “Gun Stock Mod For the Super Tune Kit" modification which is precisely drilling a 1/8" hole for the power adjuster. That service can be found here.

When you place the order for the above-described service, you will receive an order received notification. Shortly after that, you will receive a second notification with details associated with packaging and shipping them in for service.

  1. Hajimoto –

    Can you please explain what it is that you are trying to achieve? The spring inside the valve that returns the poppet or the hammer spring?

    Gauntlet STK

    Super Tune Kit (STK) for Gauntlet 1 and 2
    $75.00 – $93.00

    THIS ITEM IS NOT DESIGNED FOR THE GAUNTLET 30
    IT HAS ITS OWN HAMMER PRELOAD ADJUSTER STOCK

    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.
    BE SURE TO SELECT THE CORRECT GENERATION GAUNTLET

    CONTENTS:

    • Adjuster Plug Assembly.
    • Smaller, Lighter Composite Poppet.
    • Hajimoto Hammer Spring (Black Long)
    • Lighter Trigger Spring (Bright Small).
    • 5/64″ Allen Wrench For Adjusting Power.

    The single largest performance increase modification item is available for the Gauntlet 1 and Gauntlet 2.
    Consider adding the o-ring kit so you have all that you need should one of the factory o-rings get damaged during the kit installation, see option below.

    Be sure to follow my written instructions in the document below.

    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 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.

    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.
