Tuning Umarex Notos has arrived.

Ok …so am I seeing this right? Are you just sticking a handle on the existing side lever? Wouldn’t it be better to just make a complete one piece replacement for the whole side lever with your bigger grip on it?

I wish that I was able to do that. The lever is steel, it's a compound forged assembly and not made from a sheet that can be simply stamped and drilled.

Titanium would be the best material by far but the price would easily eclipse the price of the Notos itself.

Aluminum would not hold up with that long and skinny arm, a cast arm would not bend but is much to fragile for that skinny of an arm.

If you have an idea, please share it, anything that could help our little community.

I have not studied the lever and dont have it in front of me now to comment on it but i would have just assumed it would be a simple part to machine with a mill, with a slightly different geometry to accommodate the attachment point for the vertical grip like other side levers are made.
But that’s what I get for assuming huh? Hahahaha Pardon my ignorance.
 
I saw these on eBay. Made for Air Arms PCP's but maybe it can be adapted to attach to the Notos charge lever with some screws from behind the lever.
These are available from other sellers as well. I copied these URL's because this chap probably invented these.

Very odd question but, what is the lowest fps someone has gotten this to?
Any luck getting to around 400 fps or so?
I ask for plinking in my small yard
Seems like someone had tuned theirs down to 500-ish fps on here not too long ago.
Using a combination of regulator adjustment and a lighter hammer spring, you would imagine that a person could get as slow as they wanted with it, although accuracy is possibly going to suffer greatly at some point.

Thanks, I just really wanted a ballpark of what it could do before I bought it.
Im only shooting from around 20 feet away so Im not TOO worried about accuracy suffering a bit. I would tune it back up when I go out to hunt/target shoot

Have you checked out the Webley Nemesis? It’s a lower powered airgun and in the same ballpark as far as price goes. They say it makes 550fps straight out of the box.
