    Stak Pak for Hatsan QE shrouds (.357 & .457 Not Included)

    Simply unscrew your shroud end cap, remove the two felt-covered stock baffle assemblies, remove the two aluminum stand-off chambers, and install the Hajimoto Stak Pak. No tools, no modifications, just a simple one-for-one swap! Some model Hatsans will use all the baffles others will need one less full-sized baffle, be sure to use both shorter baffles and leave out the full-sized one. If you need to leave one out, leave out the very first full-sized baffle and then arrange the stack as shown in the packaging.

    A ten-piece kit that directly replaces the two hair curler style baffles that come inside any Hatsan that has a QE shroud system, excluding .357 & .457 models. The bundle has nine baffle chambers to help remove both noise and turbulence in the air stream. The baffle stack rides on a high tension compression spring allowing for a perfect fit for any Hatsan QE PCP, excluding .357 & .457 models.

    The end result is a more laminar air stream which reduces projectile instability and substantially changes the sound of the report of the rifle. This kit is 100% compatible with the stock end cap or the DonnyFL A24 adapter.

    This is a direct replacement end cap that when installed provides 1/2 x 20 UNF threads to allow the installation of your favorite moderator or suppressor. If you are looking for a better and stiffer barrel to barrel shroud connection that helps eliminate point-of-impact changes or projectile clipping issues, consider going with the A70 Adapter which essentially marries the barrel to the shroud.

    If you are a Hajimoto Productions Strip Stak Pak (SSP) user, then stick with the A50 because the A70 will not work with the SSP.

    Strip Stak Pak for the Benjamin Akela and Kratos PCP’s
    A nine-piece kit that includes an efficient multiport air stripper that strips and channels air away from the pellet to allow for a more stable and less turbulent pellet launch from the muzzle. The kit also provides variable-sized baffle chambers to help remove both noise and turbulence in the air stream. The end result is a more laminar air stream which reduces projectile instability and as a secondary benefit, reduces the report of the rifle. This kit is 100% compatible with the stock end cap or the DonnyFL A8 adapter.
    The Air Stripper is threaded and comes with an o-ring and silicone grease for installation. The stock barrel shroud spring must be reused.

    DonnyFL A115 JTS Adapter

    JTS Airacuda Adapter #A115
    $50.00

    Specifically for the Airacuda Standard or the Max in any Caliber (.22, .25, or .30)

    Because this adapter was made to fit both the Standard and Max versions of the AiraCuda, and because of the variations between individual rifles, you may find that one or two threads remain exposed when you snug the adapter in place. This is normal, and will not affect the performance of the rifle. In fact, our testing has revealed that a longer or heavier moderator can be used with less risk of clipping as compared to the endcap-only style adapter. It was necessary to design with this flexibility to overcome the challenges of this airgun’s shroud design so that moderators could be used.

    Key Features:

    • Compatibility: Perfect fit for JTS Aircuda and Aircuda MAX rifles. Suitable for .22, .25, .30 caliber variants.
    • Premium Material: Made with high-grade 6061 aluminum, ensuring durability and a lightweight feel.

    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
