    Is the 10.5 inch Emperor v3 still too loud for you? If so add this 6.25 inch expansion chamber to the rear of the Emperor to make it even quieter. 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.

    Super Tune Kit (STK) for Gauntlet 1 and 2

    Gauntlet STK

    Super Tune Kit (STK) for Gauntlet 1 and 2
    $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

    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.

    Full-fledged 2-stage trigger for the Umarex Gauntlet 1, 2 or G30. This trigger is a direct replacement for the single-stage trigger that ships with the Umarex Gauntlet. This trigger is a straightforward install that will increase the accuracy of your shooting due to a more predictable and consistent breakpoint.

    • 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.

    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.

    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

    Ninja X Reg Custom Output Regulator up to 3100psi

    Ninja High Pressure 5/8″-18UNF Custom Output Regulator
    $144.95

    5/8″-18UNF thread can be used on 3000PSI bottle as well. This regulator is built with the ball/pin and spring removed so hot swapping will not be able to happen.

    We do include the ball/pin and spring should you happen to have a thin pin depression system capable of actually opening the valve. The only function of this pin/ball is to allow the tank to retain air if it is off of the PCP. This is a paintball thing and should not be used in in HPA.

    You should never try to unscrew a high-pressure output paintball-style regulator while it is under pressure. You will destroy the threads as they are not designed to be threaded on and off under load. Degas and then remove the regulator and bottle.

    A 13ci aluminum 3000PSI cylinder with externally adjustable Ninja Flex Reg with typical G1/2-14 threads connects to your Umarex Gauntlet 1 or Gauntlet 2 without any modifications!

    The diameter of the tank is 54-55mm across so a modification to the forearm is required on a Gauntlet 1. I do offer a tank shroud modification service for Gauntlet 1 owners that can be added to a build or provided as a mail-in service.

    The Gauntlet 2 forearm slide right over without any issue. Only one access hole needs to be drilled so the fill port is accessible at the bottom.

    Consider picking up our extended foster fill adapter to make coupling and filling a breeze.

    The Power Flex Combo allows the user to externally adjust the regulator output pressure on the fly with an adjustment range of 800PSI!

    When installing the Flex 13 on the Umarex Gauntlet. Tighten the degassed tank and regulator assembly fully to the rifle, then back it off until the fill port is on the bottom and the gauges are left and right. Now fill the bottle with air and all will tighten up solid. Proper alignment will be achieved before the 360° maximum rotation limit is realized.

    Comes with a dedicated Spanner Wrench for power adjustment. MADE IN THE USA!

    Because of practical limitations, regulator output will be +/- 50PSI (3.5bar) within the requested output.
