I have a rifle with a 16" carbine length black nitride barrel.
Very accurate and gas port appears to be just the right size. I run an A5 -1 buffer in it.
I know I can get them in stainless, black nitrided stainless and machine gun steel nitrided.
PM me if you want info on where I get my barrels.

That's a hell of a price for the Sionics barrel! My LW barrel is 223 wylde only because it was a free T&E unit. Retail on the one I have is $295.00. I knew Sionics use LW barrels when someone posted that the barrel manufacturer won't print anything on the barrels.
Bravo Sionics, these barrels are nice.
Why Wylde? Are you going to get a match/fitted (headspaced) bolt with it as well? The Sionics barrel is one hell of a deal under $200.
Nitride, when done to carbon steels, results in very corrosion resistant as well as very hard, durable surfaces. IMHO, stainless steels are a poorer choice for salt bath nitriding processes because the different elements in the stainless alloys result in reduced corrosion resistance, as well as lower heat resistance that's inherent in the underlying steel. Nitrided stainless means more expense for a poorer performing product. Why bother to nitride stainless when CM/CMV steels are less expensive, stronger, more resistant to heat, last longer, and more corrosion resistant after nitride.
I run an AR Performance .223 Wylde barrel on one of my guns. I really like it and at $210 it's a pretty good deal.
However, I wouldn't shy away from the Sionics barrels either.
ARP? They use standard 1/2-28 for muzzle threads on the 16'' like everyone else:

Wait What? There are companies making .223 caliber barrels with 5/8-20 thread pitch?
That is nuts. For what it's worth Bergara makes nice barrels. We've run two of them with good results.
The both shot 1/2 MOA with 77 gr SMKs. They're both still in the shooting rotation, but are less than 2 years old. Both are Stainless, but one came with the black finish. I forget what they use, but the black barrel took a little longer to settle in and shoot 1/2 MOA. The plain SS barrel shoot great right out of the gas. Both are gassed good.... i.e. the ports aren't oversized.
Here's the thread I started when we first put them together.

IIRC, Stainless is only accurate because the rifling is formed (cut/button/whatever) to the exact specifications of what it should be, while any barrel that will be chrome lined has to be made slightly larger to take the lining into account, which causes some accuracy degridation. There's no reason a carbon steel barrel without chrome lining can't also be just as accurate.

Damn it seems that bergara dropped a ton of barrels off their production line
Here's what they say about the 5/8-24 thread:
NOTICE*** THIS BARREL HAS 5/8-24 threads to keep the bore at the muzzle from swelling like most barrels threaded 1/2-28. The tighter bore at the crown gives better accuracy.
Anyone hear of 1/2-28 threaded muzzles swelling? Also might not be ideal if you are the type that changes muzzle devices more often than you change your underwear.
I've heard this from our riflesmith. When he threads a bolt gun, the does something to minimize this issue.
It's also true of these sporter hunting guns where they turn the barrels down too light. The bore diameter increases. Apparently when the barrel button is pulled through the barrel tremendous stresses are put into the steel. Then if you come along and remove a bunch of the external barrel steel, the bore will actually open up some.
(forgive me barrel manuf gurus if I'm hacking this explanation to bits)
