The Umarex Zelos PCP Air Rifle is a platform with adjustable features engineered for precision shooting, with a bullpup design for maximum efficiency. Capable of velocities up to 1100 FPS in .22 and 1000 FPS in .25, and power up to 26 FPE in .22 and 36 FPE in .25, it provides the necessary accuracy and power for plinking, small-game hunting, and target practice.
The bullpup configuration of this air rifle means that it has the velocity of a larger model in a shorter and lighter package, so it offers excellent maneuverability and easy handling, making it especially suited for carrying on a long day in the woods or field. For quieter shots, the barrel includes a 1/2″ X 20 threaded muzzle for adding an external moderator.
The Umarex Zelos utilizes a 250cc air cylinder that fills to 3625 PSI (250 BAR) to provide ample shots per fill, combined with a receiver-housed adjustable regulator to deliver customized tuning and ensure that each shot leaves the barrel with consistent and predictable velocity. We also offer a bottle conversion setup that allows you to use a 300cc, 360cc, 500cc or the monster 700cc carbon fiber bottle that hold 4500PSI. The bottle conversation is a custom regulator that reduces the 4500PSI down to the stock 3625 which means a massive amount of shots between refills!
For a comfortable and slip-free hold, the stock offers a ridged rubber buttpad and a textured ergonomic pistol grip.
To enable precise shots, this air rifle comes with a 21-slot Picatinny optics rail on top of the receiver for adding a scope, and it also includes an 8-slot Picatinny accessory rail under the free-floated air cylinder for attaching accessories such as a bipod, light, or laser.
The Zelos is an airgun with flexible features and the power and precision needed for small-game hunting, target practice, and plinking.Â

Hajimoto Productions Strip Stak Pak for the Gauntlet 1 or 2. Not compatible with the Gauntlet .30 Caliber.
An efficient multiport polymer 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 HP Air stripper 2.0 comes with an o-ring. The kit also includes variable baffle chambers to help reduce both noise and turbulence in the airflow. The result is a more laminar air stream, which reduces projectile instability and, as a secondary benefit, reduces the report of the rifle.
BAFFLES CAN NOT BE USED WITH DONNYFL SHORT SHROUD
Because the Short Shroud is cut at a length that is a perfect fit for the air stripper and the spring. There is no room for the baffles in the DonnyFL Short Shroud.
Polymer Air Stripper comes with o-ring and silicone grease for installation.

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.
