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.

We completely tune your supplied Gauntlet 1 or 2 Bolt or SL Version, which includes everything listed in the section below.
The service includes a very detailed, time-consuming incoming inspection report with photos and other relevant information detailing the condition of the airgun and all of its parts. This report is provided to you, and it must be reviewed and authorized for the work to continue.
Ordering procedures:
Shortly after the order is received, you will receive an email notification containing shipping information that will include labeling and packaging requirements.
To better understand how the Gauntlet is transformed from a static you get what you get type of airgun into an adjustable-power and tunable PCP, take a look at this video that demonstrates how the power adjuster works if you should want to increase or decrease the power output for any given ammunition to get it to fly at the best rate of travel for that particular ammunition.
HOW TO ADJUST POWER WITH STK
We will build your order based on the information provided from the questionnaire as well as any specific requests, and before the airgun ships, any credits or additional charges will be settled.

Air Stripper, Tension Spring and Baffle Stack
UPDATE: 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.
