Umarex NOTOS Owners and modifications:

[Airgun Al]

The Notos seems like a inexpensive, short, accurate airgun option.
Plenty of satisfied owners here, performing their own modifications.
Most these mods, seem to be focused on increasing the air capacity, by attaching a bottle.
Personally, I am more interested in increasing the power, while still maintaing decent accuracy....
Im courious if anyone is increasing the FPE and if so, by how much, and still maintain resonable accuracy???

 

[Firewalker]

I've converted a lot of Notos for customers and I offer a porting package that has not affected accuracy negatively. Porting though is not really an option with the OEM air tube however, there isn't enough air in the tube for many repeated shots as porting will allow for a lot more to be used per shot.

I shoot mine bone stock and love it. I'm looking into mods, I'd like to add the BR grip housing and change it over to full AR mode sometime though.

Did they announce a new rifle, very similar to the Notos, but much more power?

The Zelos?

Twice the weight, Twice the power. There is no free lunch..

There is even a fx barrel kit available on ebay. But the more you mod it, the more it becomes a cheap gun with a whole lot of mods. At that point why didn't you just get a more expensive gun to start with?

Well I didn't say it's not fun. I've played with mine a bit too.

There has been good news as of late. Without doing any porting and/or permanent changes, I have been able to increase velocity from 740fps to a whopping 812fps with just an FX liner/barrel kit from c88machining on ebay.

This was achieved with a 700mm liner while the 500mm liner gave a solid 800fps.

In the near future, I will be modding a brand new Notos with full 5mm porting through all the receiver, air block and transfer port, the custom made thimble will utilize multiple ports for full use of all the new air.

The wanted result of all this will be to make a modular, easy to build, step by step, full power air rifle that will reliably shoot at 100y with the pellet or slug of choice within the confines of the available magazines.

OK, today I started with a new in the box Notos, I ported it front to back at 5mm, twin thimble ports at 5mm as well.

2900 psi regulator with the stock hammer spring and got a whopping 915fps with CPHP's!

I figure that once I change over to the Z-block, put a plenum on it and a bigger bottle, I should be able to tune it and settle on a pellet for her.

I stole the mod, drop-block, reg and bottle from my EDS but she will be getting them all back when I switch over to the Z-block.

If they came out of the box, from the factory, shooting that hard, I would own one!
Nice job!
Looking forward to accuracy results.

The whole point to what I am doing is to create a #6, nearly silent slug shooter. I hope to make this version available for sale soon.

I took it out tonight in the rain and popped a Starling and boy, let me tell you, the sound the pellet made at 50y hitting flesh was the reward I was looking for!

The sound the gun makes with the subscriber moderator insert is purely mechanical now.

 

[Firewalker]

Looking forward to accuracy reresults.

It's raining here so only indoor results are available but 15gr JSB's are a ragged hole at 900fps.

Shooting birds at 50y is much easier now, much flatter than 750fps.

very nice set up

My younger brother is always wanting more power for his Notos. This rifle has a Reximex Turmenta 15.4" barrel (390mm) and action block opened to 4.8 mm along with the barrel port angle 11+ degree. Reg at 2100 psi. This is the biggest plenum I've made @ 32 cc, middle is 25 cc and bottom is 15. Just south of 30 fpe now. Tank is an Airmega 100cc @ 4500 psi with modified end caps for additional 12 cc. Still a very compact carbine at 29" w/o the moderator attached.

How did you add your own mod?

 

[Healthservices]

It's not really completely a notos. Look closely and you'll see it is in 177. The SnowPeak PP750 is basically the same gun.

We have either replaced the factory barrels or have cut and threaded the Notos barrels.

I thought I see an adapter that threads on the shroud. Is that not possible?

<p>This is a Umarex Notos plenum kit. The kit consist of 2 shroud end caps and a 15cc plenum. Orings are already installed but spare ones are included along with the barrel orings. The front end cap adapter has a 1/2x20 unf thread that simply slips over the barrel and is drilled and tapped with...
