Nice! Your Notos looks great!
Did you do the machine work to put the LDC on? I don't have the ability to do that and would love to find someone to do that to my barrel. The carbon fiber tube over the barrel is a nice touch!

How much quieter? My stock Notos was 91dBA I use the short 3d print and it drops to 87dBA. And that drops it down to hearing hammer slap lol.

Nice. Is that the CARM magazine you have there? Does it have any binding up issues when loading?
The stock magazine I have occasionally has a rough loading/jamming issue.

Amos,
Bullysyclone did the machine work. The recrown improved accuracy.
miksatx,
I don’t have a sound meter. Just hear the impact on the wood backstop.
pnw,
The 4 Carm mags all work smooth with no binding when loading.

About a week ago I decided to get a pcp for intown plinking and immediately found myself paralyzed in the rabbit warren. Started off wanting cheap one day and MX the next, knowing it could never stay cheap (this ain’t the first rabbit hole I fell down). So while drowning in info and choices yesterday, I read the first 5 or 6 pages of this thread and ordered what might have been the last known Notos available, with a few packs of crosman 14.3’s and etc. I have lots of steel hundreds from cave diving, so will just supplement with a hand pump when necessary. I came here to introduce myself, because this thread is where I found my first final solution. the Notos just has the it factor, and I’ve yet to touch one. So thanks to all who post here. I am looking at the end of week at the earliest, but I have lots more reading and buying to do so I’ll be seeing you.

Jemkewl,
Yes, the stock barrel was shorten 1/2in. and threaded for an air stripper/endcap so the cf shroud is functional. The end cap is threaded 1/2x20.

Got my Notos put together, high rings came this morning. Got to fix the trigger. Can I remove and polish the adjustment screw without removing the trigger group? Instruction indicate I can. Is there anything else in there beside the screw.... like springs, washers, etc? How long is the screw?

Yes not a problem screws right out. Just the screw alone on mine. You’ll want a drop of vibra/lok-tite on it too. Mine was loose as a goose after first removal!

Just got my 3rd Notos put together last night. This will be made into a 25 cal later as I am waiting for a barrel blank from Slovenia. I went to a different direction on this, rather than a drop block for a carbon bottle, I wanted to try 2 tanks coupled together. This has net 152cc volume. It's still in 22 cal while I try to make a 25 cal magazine for it.

I made a few batches of custom .25 stormrider magazines for Wes last year. I believe they should work fine with some minor modification. Let me know if interested.

I cleaned the stock with brake cleaner to make sure no oil residue was left, then used a rattle can spray I got from Amazon.
The coupling I machined out of 7075-t6 alloy same as the end cap, only double sided. This material is ASTM 210M rated and are the only ones I use for my drop blocks and adapters. My other guns are posted starting pg#24. You can also see all my mods on facebook umarex owners group.

The plastic pic rail is held by one allen cup screw on top of the action. Under this screw is an M4x4mm set screw which holds the barrel, it's a 2 mm allen wrench and may be tight due to thread locker. One of my gun I had to use electric soldering iron to heat it up and keep stripping the set screw. Both barrel ans shroud will slide forward, you can then separate the pic rail from the tube and barrel. It's a good practice to mark the moderator with a scribe to the pic rail so the transfer port will be align on re-assembly.
