Tuning Umarex Notos has arrived.

I like the Notos but I want people to confirm how accurate it is.

The Notos already has some bad stuff going against it like the various things they used to prevent actually modding and improving it (non-removable moderator, loctite in various screws, etc).

If it were accurate with cheap pellets I might buy it anyways.
The accuracy of my Notos will not necessarily be the same as the next guys Notos and so on…. No one can promise you a certain level of performance with any particular airgun without testing that exact airgun.
It’s a low powered rifle with a barrel less than a foot long and a very small air reservoir…. I’m sure many would like to see match grade accuracy with the cheapest pellets on earth and the whole thing selling for about $250. But that’s not realistic.
If you are already having issues with features that you don’t like….then maybe you should just buy something else? Why buy something you already aren’t happy with?
This thread isn’t here to act as a sales promotion. It’s an information dump.
I’m just happy to be here discussing it with other pellet gun nerds that own it like myself. I’ve no inclination try to talk someone into buying this thing! The people that want it are already lined up for it and are waiting for it to be in stock again.

Thank you for replying.

I already have the PP750 in .177 and I think it is a great air pistol/carbine.
I was hoping that the Notos would be at least as good (still hate the non removable silencer).
I bought the PP750 in .177 because I knew that the Notos would come and is in .22.

I really want to buy the Notos but I need to know how accurate it is :)
 
Without the carbine stock it measures 22inches.
Without the carbine stock and if you were to remove the moderator it looks like it would measure about 16 inches. View attachment 320857View attachment 320858
thank you for the dimensions.. I'm going to order one with the grips and open sights and then promptly remove the moderator.. I saw another post and they removed the shroud and barrel.. the rear screw for the rail has a set screw underneath it and it is all that holds the barrel on.. and I saw that it appears to have a plug on the bottom of the moderator so I am assuming that it's hiding the set screw holding on the moderator.. I am going to try to figure out a way to remove the moderator and machine 1/2x20 threads in it and also a adapter for the barrel.. that way it's easy to change and if someone wants to they could easily put on a Donny FL.

Kinda bummed I don’t think you can remove the barrel because of the moderator because it appears to be staked in. Also the shroud covers the bolts that air cylinder block. Does any one have any ideas how to remove the block at least with out damaging the plastic shroud.

so in your bottom picture I believe that pin is just a plug or cover.. if you remove the rear rail screw it's got a set screw underneath it and if you remove the set screw the barrel assembly slides off.. I'm quite sure that the plug on the moderator is just a cover for a set screw.. I plan on ordering one and I will put a small drill in the press and set a stop.. hopefully the plug will come out with a easy out.. then I plan on trying to convert it to screw on.. 1/2 x20 threads.. so if someone wants to put a Donny FL on it hopefully it won't be hard.

I finally got through all the posts.. looks like someone already cut the moderator off.. and got a different after market moderator and cap.. looks like the original one is molded in snap rings instead of a grub screw.. so I guess I'll be cutting off the moderator too, but I will probably machine a threaded adapter for the barrel and then epoxy a matching threaded adapter to the factory moderator.. that way I don't have to buy a new moderator and I can just unscrew it.. I don't know how to post pictures here but if anyone can tell me how, I wouldn't mind sharing what I do since apparently I am not the only one who wants to shorten it.. and yet it would be nice to be able to screw on the moderator if I wanted to.. the gun with the moderator is just too long as a pistol for a holster.

Look at post #152 boomstrike has pulled a moderator apart with pictures. He mentions finding 2 c clips.

Ah, I didn't see the barrel length difference.
Here is some more interesting stuff. The hammer weights are about the same and the springs are too. Same wire diameter of 1.10mm

Well the spring length is a little bit different 62mm to 65mm free length difference. So I would assume a fair amount could be done by changing some of that stuff maybe?

Ok using the lower reg pressure air tube from my 177 that was set at 100 bar I get about 694 fps with the lighter jsb jumbo rs 13.43 gr pellets in the Notos 22. Exchanging the hammer spring to a smaller wire diameter of .090mm I was able get to 629fps and 580fps depending on spring presure. It is a lot quieter. This is also with the stock 177 PP750 regulator at 100 bar I have no idea if the Notos can regulate well down at 100 bar. How many shots is considered enough out of the stock tube out of a .22 ? With a full fill.
20230128_142444.jpg

I shot this at 34 yards. 3 inch targets.
20230128_141651.jpg

5 shots each target. Starting from the middle right. 🤪

The groups look bigger than they are because of the splater targets. I think all are less than a inch and a couple are pretty good.

20230128_153248.jpg

First time I have shot so many shots with this gun in one sitting. For that matter this has to be within the first 150 to 200 shots I've done with the Notos. All on one fill with some left over.
20230128_152758.jpg

I used the single shot tray and because I have a hard time keeping count I have to lay out the pellets in batches of 5. I still messed up on one as I shot six.
20230128_143106.jpg


The shots stayed between 640 and 630 for a very long time.

Not bad for lower speeds, huh?

Nice. 75 shots with a sd of 3.7…. That’s a lot of shooting for such a little air tank! If someone was doing indoor 10m shooting that would be just the thing.
I think for what I would like to use mine for I can sacrifice shot count for a faster fps and higher energy. 700ish fps with the 18s is pretty nice. Plenty of power there for little critters.

There is nothing negative about the Notos in my book. i have shot squirrels at 50 yds with hades and I think that is not what it is designed for. It’s a close range, no need to fiddle around with lightweight and accurate pellet rifle. If you feel the need to modify and add parts to a Airgun to make it better than buy a Fx Airgun they Are a modifiers dream. And yes I own two FX’s
Squirrels at 50 yards, that means it a capable gun and you’re a good shooter. I’ll be following this one to see how it’s doing in a few months or a year down the line. You can do a lot with sweet mini carbines like the Notos. My Atomic XR has spoiled me for anything longer or heavier. And it too is capable of DRT squirrels at 50 yards. The fact that you can easily charge the mini carbines from a hand pump is also a big plus. You don’t necessarily need to buy a HPA compressor. Am hoping they make the moderator removable on future versions. Then I can run moderators of my choice, it also make for easier barrel cleaning. Looking forward to hearing lots more about the Notos.
 
Leon, if your Atomic is anything like my Concept Lite was trigger wise the Atomic is a better trigger setup. The Notos spread and velocity with 14.3 is great but the trigger is not a bench trigger. For the price it is a great price point but at the same price point the Gamo Urban is more accurate, has greater velocity, and has a better trigger. But as you know the folks picking the Atomic or the Notos are doing so to fit a niche or different need. If I had to use a “stars” system I would give trigger setups and 50 yard setups similar to this — I have owned or own all these PCPs:

10 of 10 - Pulsar/Renegade
8 of 10 - Concept Lite/Commander
8 of 10 - Gamo Urban
5 of 10 - Notos
 
Based on the comments about 50 yard accuracy it seems that the Notos is not accurate enough at that range.
Umarex Notos (like the Benjamin Marauder Pistol AKA Prod) seems to be intended for about 30 yard targets.
Depends on what “accurate enough” means to the actual users. It’s understood that they are not bench rest guns. It’s up to the shooter to determine their own limitations. Don’t buy a mini carbine to go long… makes no sense. If it can make sure kills on small game, out to 30-40 yards? That is very good thing. Plinking? Take it as far as you want…
 
L.Leon and nobody2 captured my thoughts well. If you want a 50 yard gun in this price range get the Gamo Urban, I own one and it is great. If you want a light weight carbine/pistol conversion that is a ton of fun as a plinker under 30 yards get the Notos.

I have zero buyers remorse and would buy my Notos again. However, it is best to understand the advantages and limitations to avoid disappointment. I dont drive a car into the lake and lament how it is a very poor quality boat :) :)
 
For me the trigger makes the Notos a plinker not a bench rest gun. I wouldnt worry about 50 yard groups smaller than a half dollar.
Out of the box it totally sucks. But with some work it can be make to where you cannot recognize it is the same gun.

Biggest contributor to a bad trigger on the notos is that sharp point on the adjustment screw on the trigger.
20230129_103042.jpg

To me if I am correct it seems to scratch as it digs in when you first pull the trigger. I pulled the screw out and rounded the tip. Then put a dab of grease on there. I later put a balled tip with a spring inside. I put the tip inside a drop of super glue and push down like 50 times to pack the spring side full of glue then I sprayed some activator on the ball so the glue would harden, cleaned off the excess and installed.

Second is the horrible heavy pull. Adjustments helped. You have to play a lot until you get there. A lighter spring helps.

3rd is consistency on the sear release. Polishing the sear points help a lot and having a little grease on top of that aids in the process.
20230122_202451.jpg

The hammer has a sear point too and is easy to remove when the handle is off. Just remove the large screw in the rear. It does have some tension so keep your fingers on it when you remove it.
20230121_161138.jpg

It catches on this lip. Polish that
20230121_161646.jpg

To something like this.
20230121_163508.jpg


3rd is lack of a 1st stage feel. I put a spring above the trigger to give the trigger some type of 1st stage where you can feel the second stage start and the sear release. Put a light spring here as one that is too heavy will not allow the gun to cock.
20230129_141906.jpg

20230129_143707.jpg

Oh make sure to have a very little dab of grease on the contact points and the pins.

All these things together make a very decent trigger. I also got all these tips from past forum tips on the PP750.

Well for S and Gs I put the notos barrel on the jet 2. Whoa!!!! I tested 2 mags with jsb 18.13 with a cheap red dot i hate red dots since I need magnification but I think I’m gonna get another notos just to be a notos and leave the barrel on the jet 2. It appears the barrel I got was bad!! Form hatsan. I need to re test with a better scope.
