Umarex Zelos upgrade

[saneroner]

From the first time I saw the RTI Mora, I was captivated by its design. Visually, it was unmatched in my eyes—futuristic, industrial, yet sleek and lethal. However, the only thing keeping me from purchasing one was its price tag. At over $2,500, I just couldn’t justify the expense for what is ultimately a hobby.

So, I decided the next best thing was to modify a Zelos to achieve a similar aesthetic. I found a great deal on a new Zelos, and that marked the beginning of my journey to modify the shroud. I started by 3D printing some threaded end caps. When I removed the shroud, I noticed a large gap between the barrel’s end and the shroud’s front, where a moderator would typically be attached. That gave me the idea to install an internal moderator and make use of that empty space.

Long story short, I replaced all the end caps with aluminum ones. The only plastic part left is the spacer at the end, which I plan to replace with a properly sized aluminum version in the future.

if you port the air from your moderator through the rear blue piece back into your shroud it will be a bit quieter..
that's how it is if you look at the airforce Condor SS.. the barrel guides or spacers have drilled passage to the middle part of the shroud,it makes use of the empty area.. also airforce only uses 3 metal baffles.
you are doing very nice work

Yes, I saw that when researching other rifles and plan to drill air ports throught the rear end cap as it is now made out of aluminum. Next I want to convert to bottle and add a guard pic rail that cradles the bottle like the Mora's.

you are doing all the things I'd want to do with the zelos.. I had thought about it but I really don't like the space between the air tube and the barrel, just looking at the picture it looks like you have a much larger shroud than the factory one so I don't see the big gap..I also looked at the snow peak m60b.. it's a zelos bottle gun..from Airgun archery fun in Canada.. it's the same gun pretty much, firewalker here on the forum has been showing a lot about it and doing conversions to bottle..
I wish the zelos was available just like the m60b.. m60b is a tube gun like your zelos..
did you put baffles in your aluminum shroud/moderator?

Yeah, the shroud is 50mm OD and 48 ID. I asked a Mora owner and that is what they said it measured. I want to add a bottle too but will have to have a Z adapter to lower the bottle down a bit in order for it to fit. Yes, I have 3d printed baffles inside the tube.

You might have to size down the shroud if you add a bottle. I can only fit a 1.2" OD shroud on my M60B.

There is a guy, Paul that posts on AGN and eBay, who released a kit to lower the bottle height and adds a pic rail under the trigger guard.

You're looking at a bottle adapter to put a 1.1l carbon fiber bottle on your snow peak or umrex zelos Bipods not included May need to change factory moderator Do not overfill. Must have metal trigger guard. Does not include carbon fiber bottle. !!!! Install video, please watch...

I have the machines to make my own adapters, just don't have the knowledge on how the internals -ports, airway? - have to be. I have to do more research but I'm sure i can machine the parts.

myself I'd want a smaller if shroud so you don't need a drop-down.. and then the bottle you can get with a valve in it and hot swap them if you are in the field..
I'll try to remember and look, seems like recently I saw a place advertised the baffles kit for around $70.. airforce uses a aluminum baffles and they work very well, although you don't see them inside the gun they are off shape.. almost like a huge pellet.
the kit also has the barrel spacers with the port holes in it, hopefully you can find a picture of them to get a idea of about what size and how many holes

I personally really like the big shroud and was the only reason i bought this rifle. lol. I want to make it look as close as I can to the Mora on a budget.

Dang nice job I really like it! If you dont have enough room for a bottle you could fab some kind of drop bracket adapter or maybe find a bigger diameter air tube you can adapt?

Yeah, I plan to either make one or modify one of those on aliexpress.

That is really sharp!
