Rated 5.00 out of 5$75.00 – $93.00Price range: $75.00 through $93.00Select options This product has multiple variants. The options may be chosen on the product pageTHIS ITEM IS NOT DESIGNED FOR THE GAUNTLET 30
IT HAS ITS OWN HAMMER PRELOAD ADJUSTER STOCKKits available to fit Gauntlet 1, Gauntlet 2, Gauntlet 2 SL, or Gauntlet 2 Limited 22/25, variants.
The 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)Â
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.
Be sure to follow my written instructions in the document below.

Notos/Notos G2 Internal Porting
Notos Internal Porting
$75.00Select optionsNotos Internal Porting
This service provides increased airflow and efficiency of the internal pathways, resulting in more power capability.
This is what we do to our Haji-Notos/Notos G2 Custom Builds, but you can have the same service performed on your Notos as well. We increase the internal transfer ports, which results in greater airflow and more power. This service also includes a trigger sear face polish to make the trigger feel much smoother.
Ship us your complete Notos/Notos G2, or just the action with the stock and barrel removed, and we’ll perform the service.
If you want to minimize shipping costs and you elect to ship just the action, follow the instructions below.
If you are shipping your complete Notos, ignore the instructions below and use your original Notos Box to ship your Notos.
- Notos Barrel Removal
Your barrel is easily removed by removing the 2.5mm pan-head screw on top of the Picatinny rail near the magazine opening. Once the 2.5mm pan-head screw is removed, there is a 2mm set screw below it that holds the barrel in the receiver block. Loosen the 2mm screw four revolutions and slide out the barrel.
Shipping
Shortly after you place your order for the service, we send you a notification with a copy of your invoice. Shortly after that, you will receive a detailed notification with the shipping information to ship us your barrel/action/PCP for modification.
Please keep in mind that if you have multiple services executed, you will be better served using our Builder service option, because it groups the services, resulting in only one shipping cost.
