    Real 2 Stage Trigger for the Gauntlet
    $110.00

    Full-fledged 2-stage trigger for the Umarex Gauntlet 1, 2, G30, bolt or sidelever variants. 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.

    DonnyFL FX Suppressor

    FX/DonnyFL 1.36 x 5 inches
    $120.00

    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.

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

    Ninja X Reg Custom Output Regulator up to 3100psi

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

    This is a genuine Ninja Paintball High Pressure X reg in 5/8″-18UNF thread that can be used on 3000PSI or 4500PSI.

    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 the PCP. This is a paintball thing and should not be used 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.

    Read more on the subject in the following ARTICLE.

    This is a direct replacement for the regulator found on the Gauntlets G1, G2, and G30 Caliber

    Take advantage of a quality regulator for your high pressure application.

MADE IN THE USA!
Ninja HP regulator output pressures in increments of 100PSI.
Simply select your desired output pressure from 1100PSI TO 3100PSI
