Umarex Zelos Compact .25 Are You Ready?
- Thread starter Firewalker
- Start date
I hit 112 fpe with a 48 grain in the 30 cal with Paul's valve kit. He makes them, so I'd think he could make one with a port sized for the 25 cal. I'd think 60 wouldn't be very hard to reach then.

Factory Valve
Has a heavy spring, a a smaller poppet, a big spring seat, and smaller throat. It's also a 4 port design that had a chamber they vent into and up into the transfer shaft.
New Valve
Removes the spring seat for more volume, bigger throat and stem, the poppet seats right at the face. That, and the conical spring that rides on the edge of the plenum, it basically makes the plenum the valve body. It's a direct open flow now vs funneling thru the spring, seat, and small poppet. The exhaust port is also angled and enlarged, and lines directly up to the transfer shaft right into the barrel.
TLDR: IT FLOWS MORE AIR!

The stock valve looks exactly like the Notos valve as does the spring.
I cant get a scale for them in different pictures.

Hey man, have you had the opportunity to see what the Zelos is capable of energy wise in
.25? I'm very interested in possibly ordering the 25 as well if its as impressive in .25 as .22.

Check out my post in the classifieds for the compact energy. The full size Zelos of course has more energy.
I'll be porting a few Zelos in the near future for those that want high fpe and to tune the Zelos to heavier pellets.
The FX barrel kit testing has gone well but it's 500mm so we still have a length limitation right now.
I'm very happy with how the .22 and .25 compacts have turned out, accuracy with popular pellets has been on par with FX similar sized guns.

Im just curious if youve been able to generate energies higher than the advertised stock tune. Is it 60± fpe capable? Ill buy it I can start launching heavy mk2 at 880+? Thanks man

Stock tune on the Zelos Compact is currently 33gr JSB King Heavy mkll at 820fps, 49.28fpe.
Porting would be needed to reach 60fpe.

That's pretty damn impressive. Considering I want the full size. Thanks for doing what you do

It's embarrassing, I spent 1350 (gun only) on a gun that I had to add a heavier hammer to do that same feat. Stock, balls out, 600mm dream tac with plenum. STRUGGLES. To get a 34gr mk2 fx pellet over 58ft lbs. I am happy with what my gun can do with a 30gr hn slug... But, it's WAYYY more accurate shooting the heavy mk2s. I'm talking from .66-1.1moa to .36-.59moa. obviously a minute is more than enough to take game ethically at distance. But that's a rarity. I enjoy long shots, it's a satisfying accomplishment... But I find the majority of my shots come in the 25-65yr range. A good ~85% come within that range. At which, the precision and consistency of the pellet is king. I'm shooting 34gr at 55fpe getting 75-85 shots per fill temperature dependant.. I don't even have to question whether or not something is on the ground in agony. If it is hit... It is done. The fact that the zelos at 45% the cost can do at least that out of the box is a really nice thing to see.

All that being said, if the zelos can match or beat, Im going to turn the zelos into the slugger/heavy slinger with the 1:16 and relegate the dreamtac to what its meant to be: A finely built scalpel with Exact kings.

Sweet compact
I ordered and recieved one of the Zelos compact in .22
I call it the Zelcom, a (FWA) Firewalker Airsmithing custom airgun.
Just set it up and shoots great. Waiting on its final scope and I’ll take some pics ,groups and comment more on how much I like it

I also received a .22 Zelos compact from Firewalker recently, with the smaller bottle and shortened barrel. His work is professional and I would not hesitate to buy from him again.
The Notos I used to have was a pleasure to shoot. Firewalker installed a bottle on that one for me. It was very light weight and quiet and accurate at short target ranges. But not have as much power as I'd like, 18fpe to 20fpe, and the flat-handled cocking lever on the Notos isn't my favorite design. I'd recommend a Notos for anyone starting out, a good all-around package for a decent price.
In general, these days I prefer compact designs under 32" and less than 7lbs if possible, and with a wider adjustable power range than the Notos had, and with an adjustable regulator. The Huben K1 and L2 and some FX models and other brands would meet that general requirement.
Some of them look somewhat similar in design to the Zelos, and almost all of them are considerably more expensive than the Zelos. My Huben K1s and GK1s and Leshiys and Crown etc. all cost me 2 to 3 times the price of a new Zelos 'compacted' by Firewalker with a shorter barrel and bottle. I haven't had a chance to shoot mine yet, just opened the box for a look a few days and am very satisfied so far.
Deciding what to buy the first few times can be so difficult for anyone who is relatively new to airgun tech. I am one of the many people on the forum who haven't ever been able to compare many different airguns side-by-side. So over the past 50 years I've needed to buy (and eventually sell most of) a few dozen airguns just to finally figure out what actually suited me personally. Started with BB rifle in the 1960s, then break barrels, and then some .177 CO2 pistols, which was a typical progression for people back then when airgun selection was very limited and power levels mostly under 13fpe until PCPs came along.
By comparison, the airgun market is simply roaring now with new tech and model releases these days.
Like the new FX Redback Gatling repeating 8-shot Gatling style airbow recently announced at gogun.co
The AGN classifieds let old-timers like myself buy a few airguns every year, not because we need them, but mostly just for the plain satisfaction of being able to try them out. I could never afford to have kept all of the airguns I've owned over the years. And I'll probably end up selling my new Zelos in the classifieds within a year or two. Some of those rifles in the classifieds have passed through 3, 4, 5+ owners by now, many of them just sat in storage most of the time and still look good and work well.
We'll start to get more feedback on the performance of the Zelos as Spring rolls around and more people get a chance to test theirs.
And possibly compare them to other more expensive brands/models with similar specs.

That looks great! My issue with the Zelos is the length of pull. I have to use a reversed cantilever scope mount on mine. I wonder if Firewalker can cut down those additional picatinny slots to even further reduce weight especially if you don't use them...

What a pleasure to shoot
I’m getting 930ish fps with 18.13 JSBs.
FWA tuned it and adjusted trigger so there is zero first stage slack.
Excellent groupings Slight Clover leaf at 20y with no bipod or rear rest. Just a front stand
New Grips and a lower pic rail are in route
