Specifically for the Umarex Origin
Not to be used with the Hajimoto Productions Strip Stak Pak (SSP) which is an Air stipper. Spring and Baffle Stack.
This version allows you to use a larger suppressor than the Tanto or KOI. Designed to slide over the barrel to keep the barrel centered with the adapter. This reduces the chance of pellet clipping and improves accuracy.

This part is designed and manufactured by DonnyFL
Avenger/Origin Mini Magazine
The same reliable design as our expanded magazine but shorter to allow the mag to fit under your optic without the need to adjust or swap out your scope rings.
The HP Mini magazine is designed to fit the Avenger and Origin in .22 and .25 calibers. This magazine extends your capabilities by increasing the number of shots before requiring a reload.
The stands only 40.90mm (1.610″ a little less than 5/8″)
The NO LID design means you simply rotate the projectile carousel and drop in each round. There is no need to preload the spring, you are winding the spring during the loading process. This fits under high-scope rings and some medium-scope rings. Your scope may need to be moved forward or back to clear the turret bell, maybe

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.
Replacement Air Stripper 0-ring is 14mm x 1.5mm
