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
