Umarex Umarex Notos Moderator Removal
- Thread starter Mr.Gadgets
- Start date
I did notice a slight improvement of 3 to 4 shots. And I have a chronographed 10 FPS improvement.
I think the plenum is used mostly to improve shot variance. At least that is what FX claims.

Does anybody know if there is a youtube video of somebody removing it just using tools the average guy would have?
Hacksaws, wrenches, a drill motor, maybe a vice of some sort?

If you don't want to save the front part of the moderator I used a angle grinder with a flap disc. I ground it down behind the 5-1/2" mark then used a hacksaw to cut a groove all the way around. I put it in a vise and the twisted the muzzle end and it came right off. That left the little piece to deal with. I cut slots in it with a hacksaw and carefully drove a screwdriver in and twisted until plastic broke. It took me about 30 to 45 minutes to have it completely off

Redcorn Outdoors has invented a slip on mod for the Notos moderator that wraps around it and secures both halves together with screws that are included takes 5 minutes to install or less. Just search for his sales site on eBay to take you there. I went with the Terminator Outdoors eBay mod under seller Dadr. You turn the rifle over and drive the two pins out of the factory moderator then pull the red baffle out and slide his mod in and line up the pin holes and insert them back in from the top and drive them back in place. It's whisper quiet and works amazing!

I've abandoned this process. The plenum is now a Gen ll black anodized unit and the barrel is now threaded to 1/2X20 UNF so that the moderator can be directly attached without the need for adapters.

I have nothing at all against mod ding the Notos, but would add, it is fantastically usable out of the box. It's not meant to be a powerhouse, unless you want to mod it. I would say the only "required mod" is trigger work, and that applies to nearly evet airgun to one extent or another.

I've decided to leave the suppressor on and dial back the hammer spring.
And maybe go with a heavier pellet. It should temper the sharp higher pitch.
Since I bought a .30 cal Maverick I haven't felt the need to make the Notos reach out as far.
The Notos is my 40 yard gun and the Maverick is for everything beyond.

I got some great groups with the FX barrel kit yesterday but the wind was brutal all day so groups were mostly a horizontal line as gusts pulled them to the side.
This 30y target with JTS 18.1gr pellets was one. Still some horizontal stringing but not as bad as others. The target red dot is 1/2".
I'll have to try another day when it's calm as I saw some groupings that were encouraging but you could see the wind pull them several inches to the right at 100y.
More later.

That's pretty cool! I'll have to look it up.
I'm using the Subscriber designed one that installs the same way. Also whisper quiet!
Looks like he has a bunch of furniture for airguns as well!

No, it’s not loud from the factory.It’s just that I would prefer to have it quieter. I think these are really great little guns. I ended up putting the Plenum on it and I haven’t got around to cutting the moderator off at this point. I may just leave it on. I just can’t pick up my mind, but the Plenum does make a difference it seems to I can’t describe it, but it seems like it the impulse is quicker or something. I really can’t describe what it does, but I have two Notos. The one I have modified has slightly more FPS. But that’s not all there is to a gun. You also have how quickly it opens and closes the valve and the amount of air that comes out in a short impulse. As I said, it’s really hard to explain, but it is noticeable. It also adds to the shot count by adding the Plenum. And speaking of plenum, that’s the reason I need to cut my moderator off or I should say I want to cut my moderator off. I installed the Plenum. It makes the air cylinder longer so you can’t put the end cap on. So that’s the reason I wanted to cut my moderator off and add the other part that I bought which is the1/2-20 thread extender that mounts to the barrel. My plan was to be able to put a Donnie FL on the gun or if I didn’t wanna spend that kind of money buy one from Buck rail. Speaking of Buck rail I highly recommend those guys. They guarantee everything they make no questions asked on any returns and they’re just great guys to deal with. Hope this helps. I do enjoy mine very much. A lot of fun to shoot and tinker with.
