Air Stripper, Tension Spring and Baffle Stack
HP Strip Stak Pak for Avenger
$47.00Select optionsUPDATE: The newer avengers have a screw-on barrel shroud and an end cap that is a two-piece unscrewable but the STP still fits and works without an issue. unscrew the shroud rather than the little screw shown in the video and simply unscrew the baffle washer array off the end cap and you are good to go.
Strip Stak Pak for the Avenger
A six 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 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 A50 adapter.
Air Stripper comes with o-ring and silicone grease for installation. The installation video for the Umarex Origin Strip Stak Pak is exactly the same so you can follow the installation video below.Replacement Air Stripper 0-ring is 14mm x 1.5mm

DonnyFL A115 JTS Adapter
JTS Airacuda Adapter #A115
$50.00Read more
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.

IT HAS ITS OWN HAMMER PRELOAD ADJUSTER STOCKThe single largest performance increase modification item for the Gauntlet. The Super Tune Kit allows complete power adjustment, opening the possibility of higher or lower foot-pounds (FPE) for whatever the user desires. Do you need only 5FPE?

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 to know the rate of travel 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 GAUNTLETCONTENTS:
