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.

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

FX No Limit Scope Rings 1″, 30mm and 34mm
$79.00 – $99.00

FX shows that they are able to innovate not just within airguns themselves, but in other areas of the shooting sports. The FX No Limit scope rings are perfect for long-range shooting as you can vertically adjust and angle your mounts so you can always find the sweet spot on your scope. These rings are also very useful if you need to have your scope higher off the receiver to allow for oversized magazines or scope camera setups.

You will want these rings if you are planning on using my Expanded Magazine.

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.

THIS IS AN AIRGUN ONLY PART

This part is designed and manufactured by DonnyFL

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.

This can be added to a custom build order or a send-in modification request. Customers who wish to send in their barrel for service can ship either the entire rifle or just the barrel, barrel shroud, and end cap. The barrel will be heavily cleaned and coated with silicone oil to protect the surfaces for the trip home.

Once the order is received, a follow-up email will be provided. Depending on the service request, the response will contain detailed shipping instructions, including the shipping address and other pertinent information required on the label for the service request being shipped to us.
This service price does not include shipping or parts. Shipping costs to return your PCP or PCP parts will need to be calculated and communicated to you before the order ships back.

The reduction of an airgun barrel typically results in a decreased rate of travel of 15-20 ft/s per inch.

Any outstanding balance must be paid before we ship out the service order.

THIS IS AN AIRGUN ONLY PART

This is a custom size that comes with FX airguns if you decide to upgrade the suppressor or if you are looking to add a suppressor that is right in between the Tanto and Tatsu. The FX/DonnyFL is the same length as the Tanto but slightly larger in diameter, comparable to the FX factory suppressor. This weighs around 4.7 ounces. Comes with a protective red tube for easy transport and storage.

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.
