Niksan I'm "learning" on the elf.

No but a Plenum is easy to make or they do sell plenums if I remember right.
Yep!

Drop down menu you can select custom.
I make my own since I have a lathe.
I should have mentioned, added the required plenum will reduce volume available for high pressure air. You'll need to run a reg pressure near the pressure of your last good shot to or lower to maximize the number of shots. Then you'll like want a weaker hammer spring best performance with lower reg pressure.
I have added regulators to two tube based aurgun. I both cases it was to reduce velocity SD not to increase the number of accurate shots.
Have tough about lowering the velocity by reducing the hammer spring more? If that isn't enough the buy a weaker hammer spring. There maybe an simpler solution then adding a regulator.
The spring store has a calculator, you can enter the parameters of the current hammer spring. The calc will give the spring rate for your current spring, for there you can search for spring with the same diameter and length an lower spring rates. The spring store has minimum order, $40 the last time order. The Elf has an anti-hammer bounce design, I am not sure how that design is implemented. It make changing the spring more difficult. Just another possibility.

The main reason I went with the Ozark is the bottle rather than the tube. With the bottle you can directly install a Huben Power Cricket Max-ATH with the 50CC plenum.

And the Ozark-TW has very nice Walnut that a bit if sanding and linseed is very nice.

How are the barrels on Niksen airgun.
Kral still offers the "Barrel Lottery" 😆 🤣 😂.

My .22 and .25 Ozarks are damn good for sub $400 guns. As good as my Bobcat or Royale, no. But they hit what I am aiming at out to my 45 yard limit. I have no complaints with build quality or accuracy.

The Niksan Escalade is a whole different subject, not barrel but bottle.
 
I have an ELF-w .22 And love it. I get 4 mags full of shots with the 18 grain, and my max is 45 yards. It's dead nuts accurate, and I've taken big trash pandas, skunks and armadillos with no trouble. I bought it myself not wanting the trouble of a regulator after issues outta a few I've got. Much to be said for more "simple".
I regulate my Ozarks, but they have bottles and the regulator is plug and play.

I've also found they like heavy pellets like H&N Barracuda.

I have a Condor that way, does make it simple.
LOVE the AirForce utility platform. The easiest and simplest platform to modify. So few moving parts, especially under pressure. And oh do they like a plenum. No pesky poppet valve, transfer port or right turns. Just a straight shot from plenum to pellet.

High flow valve, heavy spring, heavy hammer, Huben Power Cricket MAX-ATH and a 24 inch barrel. You can get .22 Barracuda Match supersonic.

I shoot the 33 grain .22 for coyotes. Smacks them down like nobody's business! I just bought a .25 barrel for my other one, I thinking heavy on getting a mod for its bottle as well.

My max distance from back deck to chicken coop is 45ish yards, so I don't shoot far, just catch them cutting across outta the woods with my night scope, and hammer down lights out.
