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.

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.

Remember to always order your suppressor one size larger for shrouded barrel PCP’s.
If you have a .22 caliber shrouded barrel PCP, you’ll want to order a .25 caliber suppressor.
The .177/.22 is for shrouded barrel .177 or direct barrel threaded PCP’s in .22.
The .22/.25 is for shrouded barrel .22 or direct barrel threaded PCP’s in .25.
The .25/.30 is for shrouded barrel .25 or direct barrel threaded PCP’s in .30. The exception to this rule is the Gauntlet .30 which is shrouded but because of the unique end cap, marries the barrel and shroud at the end.
The Tanto, Tatsu, FX, or Sumo are not recommended for the Gauntlet .30 caliber because of the relatively small internal volume of these suppressors and the elevated operating pressures of the G30. We recommend the Ronin be used on all of our G30 Builds.
Hajimoto Productions Regulator Shim Kit For Umarex Gauntlet
I have put together a very easy and complete stainless steel shim kit so you can adjust your Gauntlets Regulator output. The shims that I have included give you a wide range of adjustability to mix and match different thicknesses to get the regulator to output exactly what you want. The shim kit comes with easy to follow instructions which guide you through the process as to what shims you need to add to typically achieve my recommendations for each Gauntlet Caliber.
The shim kit contains:
To take a stock G1 .177/.22 from the stock 1100-1050PSI to my recommended 1350-1400PSI you would add two (2) #5 shims (10).
To take a stock G1 .25 from the stock 1900-1950PSI to my recommended 2100-2200PSI you would add one (1) #3 shim (3).
The included two #2 shims are for minor adjustments if you have a finicky regulator.
DETAILED LESSON/EXAMPLE:
Let’s say your .22 Gauntlets regulator only puts out 1300PSI after installing the two #5’s when it should be 1350 to 1400PSI, you would add one #2 for a total of 12 to help get it there. If after the addition of the one #2, you’re still 50psi short so you would pull out the #2 and use the #3 for a total of 13.
Always use a regulator output tester to confirm the output pressure of your regulator. It is the only safe and sure way to properly adjust the pressure of your regulator.
You have to fill and purge so the Belleville washers settle into the new preload. Be sure to slow fill your bottle the first time only to 500PSI and then purge it, fill slowly a second time to 1000, and then purge fill the final time slowly and watch to be sure the reg has settled and does not exceed your target pressure. If it does exceed your target pressure, stop filling, purge and shim less.
If you rapid fill, there is a good chance you will pop your burst disc.
