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

FX shows that they are able to innovate not just within airguns themselves, but in other areas of the shooting sports. The FX No Limit scope rings are perfect for long-range shooting as you can vertically adjust and angle your mounts so you can always find the sweet spot on your scope. These rings are also very useful if you need to have your scope higher off the receiver to allow for oversized magazines or scope camera setups.
You will want these rings if you are planning on using my Expanded Magazine.

If you are looking to add an externally adjustable reg to your Gauntlet 2, take a look at swapping your current fixed reg to the Flex reg found HERE
Installs on the Gauntlet with minor tank shroud modifications. (The Gauntlet 2 is shown to give an idea of what modification needs to happen and that is simply a hole drilled in the bottom of the plastic tank shroud for the fill nipple.

A 22ci aluminum 3000PSI cylinder with externally adjustable Ninja Flex Reg for your Umarex Gauntlet1! The volume of air in these 22ci tanks over the 13ci is mind-blowing!
The diameter of the tank is 54-55mm across so a modification to the forearm is required on a Gauntlet 1. I do offer a tank shroud modification service for Gauntlet 1 owners that can be added to a build or provided as a mail-in service.
The Gauntlet 2 forearm slide right over without any issue. Only one access hole needs to be drilled so the fill port is accessible at the bottom.
Consider picking up our extended foster fill adapter to make coupling and filling a breeze.
The Power Flex Combo allows the user to externally adjust the regulator output pressure on the fly with an adjustment range of 800PSI!
When installing the Flex 22 on the Umarex Gauntlet. Tighten the degassed tank and regulator assembly fully to the rifle, then back it off until the fill port is on the bottom and the gauges are left and right. Now fill the bottle with air and all will tighten up solid. Proper alignment will be achieved before the 360° maximum rotation limit is realized.
Comes with a dedicated Spanner Wrench for power adjustment. MADE IN THE USA!
Because of practical limitations, regulator output will be +/- 50PSI (3.5bar) within the requested output.
