This increases the air volume that gets captured inside the suppressor. Works with the latest version of the Ronin as well. If it has the grooves in the front cap, it’s the latest model.

    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. (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

    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.

    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.

    • The Trigger Is Stainless Steel 17-4 Through Hardened
    • The Trigger Shoe Is Aluminum 6061-T6

    Please see the installation video below for more details.

    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.

Comes with a protective red tube for easy transport and storage.

    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.
