Umarex Zelos Question

OldVet said:

Is anyone using the regulated Huben bottle adapter, and how is that working , so far.?
Also is anyone using the Huben with a 700 cc bottle , and how's the fit.
Any pic's would be great.

Don't have a Zelos but I have a lot of Huben Power regulators.

It is a Huben, it will work.

I like that reply very much Haji is selling them for $150. Of course like you I turn my Zelos into a boat if I could , but my c88 bottle adapter is leaking right now I just need some of those 8mn part metal part rubber seals for it, and a 8mn air guage.

I have a whole kit of the bonded sealing washers.

Prime Day ends in a couple hours, 20% off.

I have ended up buying more M10 and M18. Handy for clocking things too.

I have the regulator with aa 500cc (0,5L) bottle....I like it...no issues, power and shot count (3mags) where I want it



The following are just test groups, as I was honing it in.....
I can do 3 mags comfortably...

This is great information thanks , but I do have a few Questions.
I seen from pics you have the HUBEN reg set to 3,500 , and you have a plenum installed c88 ?. I could not see what you had the reg set to on the digital guage ,and what is the brand of it , and how do like it.? , and is it set the same for both shot groups.
What are the grain weights of the JTS
pellets, and the NSA slugs. My next rifle just may very well be a .25 Zelos.
It would be a 250 Z in .25 , but for me at least using a bolt would be like taking a step back in time. I'm 65 , and used bolts for many years. I like the side lever , so much I wonder why a .22 LR Was never made with one. I seen stinger written on the rest in pic , and love the way it holds the Zelos will look it up , and try to find it gotta have one.
What bottle band is that. Hope not too much to ask. OV.

Never Too much! I'll try my best to answer:
Huben reg is set to 3400 psi (preset from factory)
Rifle reg is set to 2200 psi
Gauge is from Ali Express (amazon was out of the 25mm at the time, and I didn't know that Mike at Backyard airguns sold them yet)
I like it A LOT...more of my guns WILL go to digital gauges! (I just put a Sekhmet on my FX Dynamic)
The weight of the JTS was 25.39 GR
The weight of the NSA slugs were 38.5 GR
Keep in mind...those were early groups...I was fiddlin with the power adjuster a lil bit through the strings
I kinda dig the rest (Caldwell Stinger , Amazon)...its not perfect (none of them are), and I switch between this one and a Caldwell Precision Turret, depending upon which rifle I'm shooting...The ever changing form factors of these guns definitely takes away the old school adage of one size (or rest) fits all!
The bottle band is Inspire Precision

Hope this helps, hope you become a Zelos owner! They really are a fantastic, sleek, lil rifle! And you are talking to a guy that probably owns in the neighborhood of 90 or so PCP's...(from low end to higher end).

Feel free to ask, if you have anymore questions! I love to help this community!
