Install Super Tune Kit

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.

Gauntlet STK
Super Tune Kit (STK) for Gauntlet 1 and 2
Rated 5.00 out of 5
$75.00 – $85.00
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.

Part fits Gauntlet .177, 22 or the .25 caliber but does NOT fit the Gauntlet .30 caliber

Stock baffle spring must be used!
Remember to always order your suppressor one size larger for shrouded barrel PCP’s. 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

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.
