Avenger/Origin Mini Magazine
HP Avenger Mini Mag
$33.00
Introducing the HP 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

Features
- An easy to load NO LID design.
- No pre-winding is necessary.
- Easy partial fill design.
- .22 = 13 shots
- .25 = 11 shots
- The magazine height is 40.90mm (1.610″ a little less than 5/8″)

Avenger Shroud Adapter
$33.95

The Newer Avengers use a threaded plastic shroud adapter which the shroud screws onto. The stock plastic mount is weak and prone to breaking if over tightened which means you cannot tighten it down adequately. This can lead to the shroud being able to move around a bit which will affect accuracy. This high-quality adapter will fix those issues and create a more consistent shooting airgun. Or just replace a broken or damaged shroud mount.

The AE Swede adapter is CNC machined from 7075 high-strength aluminum part and utilizes two set screws. You can clock the piece however you want and do not need the stock barrel detents to lock in place. This helps when holes have been drilled in the shroud at the rear for extra sound deadening ability.

Liberty/Aspen/Avenger/Origin 1/2 x 20 #A50
$40.00

Fits the Nova Liberty, Aspen, AV Avenger, and Origin PCP’s

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.

HP Strip Stak Pak for Avenger
$47.00

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
