If I plan on only shooting suppressed what are some good barrel recommendations? Should I go with a mid length 18 or a 20 with rifle length gas system? What sized gas port should I look for or avoid?
The guns will be used for hunting, but 99% of the time from a truck high rise. Weight is not a great concern as the guns are fully supported by shooting chairs with arms and hog saddles.
I prefer sub MOA barrrels. Ideally two barrels that would shoot the same load accurately.

I would recommend the T-Box barrel if you are wanting to get the most accuracy out of it.

Either way I would run rifle length. If not check into the satern liberty line then over to ballistic advantage or faxon.

LaRue upper kit. With his suppressor. Can't beat it, especially when it's all been built and designed from scratch for each other. And sub-moa repeating is easy. Very little blowback and gas ejection, no splatter. Rounds show soot, but nothing like others I've seen. Upper kit and suppressor can be had for ~1200 bucks after the can discount. If that's still being offered.

The standard $500 Olympic-grade drop-in barrels from reputable manufacturers like Lilja and Shilen. Or a barrel finished by Precision Firearms (specify Bartlein or Krieger). Krieger offers a finished 20" from their website but you would have to get it threaded yourself. Plus theirs is a heavy profile requiring a 0.936" gas block which may or may not interest you. You can take a risk with lesser known brands like 'T-Box' (never heard of them). They might be good but at the same price as an Olympic manufacturer then I am unsure what the upside of the risk would be.
If the gun is going to be supported then length and weight of barrel is not so important - Shooter's choice, bearing in mind the suppressor will make it longer by 6-8".
For a suppressed rifle I would go with whatever gas port configuration comes with the barrel and use an adjustable gas block to tune the system.

Also, I only shoot the 123 grain SST as I hunt both hogs and coyotes. They seem to be the most economical, effective hunting round I have found so far.
I already own two of the Larue Ultimate upper kits with their lowers. I am having trouble getting one of them to shoot anything well so I am considering changing the barrel. I have probably 200 rounds through this barrel of factory 123 SST as well as hand loads with 8208 and CFE. One upper shoots ok while the upper has been a struggle.

Hmmm. Sorry to hear that, have you contacted Leander about it yet? They stand by their products performance being able to meet their customers demands. They check that every barrel that leaves the floor beats 1 moa, are you not seeing that?

I have talked to Larue and they have been excellent for the most part. I am shooting 2 groups at best at 100 yards with one of the uppers. Usually worse than 2. Same time, same situations, same scope setup I can shoot 1 inch groups or better at 100 yards with the other upper.
I just did not want to have to work up two different loads for the two different uppers. Though I have tried several ladder tests and OAL tests with this upper without finding an accuracy node. I was pretty much to the point of just getting a different barrel. I could have already paid for half a match barrel by now.
