Super Tune Kit (STK) for Gauntlet 1 and 2
Rated 5.00 out of 5$75.00 – $93.00Price range: $75.00 through $93.00Select optionsTHIS ITEM IS NOT DESIGNED FOR THE GAUNTLET 30
IT HAS ITS OWN HAMMER PRELOAD ADJUSTER STOCKThe single largest performance increase modification item for the Gauntlet. The Super Tune Kit allows complete power adjustment, opening the possibility of higher or lower foot-pounds (FPE) 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 to know the rate of travel of the projectile. (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 GAUNTLETCONTENTS:
- Adjuster Plug Assembly.
- Smaller, Lighter Composite Poppet.
- Hajimoto Hammer Spring (Black Long)
- Lighter Trigger Spring (Bright Small).
- 5/64″ Allen Wrench For Adjusting Power.

Super Tune Kit Users
You must use the stock trigger return spring with the two-stage trigger as the trigger spring that comes with the Super Tune Kit is too light to be effective with the two-stage trigger.
