Agree adding a plenum extension would be a good solution I just haven't found any long enough. Only one I see to purchase is only about 1.5in in length. Google search continues.
Are you looking for higher shot count? Because the plenum extensions will only give you 6-7 more shots, and a 20-30fps increase if you get all 3. But you will need to change the stock barrel for the fx barrel kit just so you can fit them all. Same thing would apply if mounting a zelos airtube.
 
The Notos reservoir = 32mm diameter.
The Zelos reservoir = 35mm diameter, and much longer.
As already mentioned, I do not believe they would interchange, without changing barrels.
Being that thick means he would also need to replace the front rail and either use the dovetail or get dove to pic adapters.

Love the pic... that's exactly what I had in mind. I'll look up that c88 kit. I like what you did with the barrel. Is there info on that somewhere I can read up on. Also thanks for the info thus far.👍
That is an FX slug liner inside the C88machining 380mm barrel kit, plus the plenum and extension as already mentioned. Firewalker cut and crowned a 500mm liner down to 380mm and put my kit together for a reasonable price.
Oh yeah, there's a gauge block on there too. I added that to increase the plenum size before any of the mods were available. You could skip that unless you really want to know the reg pressure.
It shoots really well out to 70yds, maybe even farther but that's the limit of my current range. That's shooting NSA .2175 17.5gr slugs at 745fps
FYI, Zelos is about the same cost as all the mods on my Notos.
