Help with build- barrel, gas tube, etc

I would get my barrel from precision firearms. My 12" krieger shoots 8 shot 0.6 moa groups. I don't see the point in an 18" barrel other then "because that's what i want". A 16" will hit steel out to 500 np and the extra 2" isn't going to change much.

If your going to shoot suppressed i would go with some sort of adjustable gas. Either with the block or a bootleg adjustable bolt carrier. To me the cost of an adjustable gas block makes it a no brainer to get anyway.

The only bullet over 123 that I would consider, hunting wise, is the 129 nosler ablr.
100-115 in lead free, 120-123 class for cup/core, hunting wise.
But I bang my steel with bigger cartridges so there is that. These are my choosins'.

Personally I have settled on most of my barrels as 20", I didn't like the blast and kick from the 16" that I had, and 20" has nodes that I can easily find.

Like said above, the barrel price depends on what you want to spend -- wait a minute!!! with that cheaper barrel you wind up spending more $$ on bullets, loads and gas for trips to the range. So your "barrel cost" as it were, is the same or higher for that cheeper barrel. I know I have gone that route in the past.
Barrel, trigger, scope/optics. These are the money parts. the rest just hold stuff together.

I suggest a lilja if you want to get it right away, they pretty much have barrels on their webite. Or if you can wait, then precision firearms...
Longer delivery times for krieger/bartlein but they are darn fine barrels. Others are decent to be sure but a step down from these ones.
I got a lilja 20", the 740 model (among others lol), but I don't plan on hiking over hill and dale like I did in my younger years lol. A 20" rig weighs about 9.5 lbs if you build it out right.
You can always add an adjustable gas block later, so far I have not needed it much for the grr even though I have a couple agb's on the shelf.

If you do go 18" then definitely get the rifle length gas. The shorter gas length has had troubles with getting the gas right. 18 or 20, rifle length for sure.

VASCAR2- thank you. I have experience with Primary Arms, and their scopes, all positive. Will have to compare 308vs 6.5G trajectories, but at least I have a starting point.

Aero Precision 18". Supposedly Aero Precision makes all the parts for Daniel Defense. Can't go wrong with that

I got a Grendel Douglas-blanked barrel from Compass Lake Engineering that shoots very well. .6 to .8 moa groups are commonplace. They delivered right when they said they would, with excellent follow-up and communication along the way.

The big jump in blanks is from button-rifled to cut-rifled. Kreiger, Bartlein, and Satern are the only cut-rifled Gendel blanks I know of.

Compass Lake has been known as among the very best barrel finishers for decades.

Aero does not make all of Daniel Defense's parts. I don't think they make any, in fact. Daniel Defense has their own cold hammer forge. They forge their own barrels. I have nothing against Aero. I have plenty of Aero upper receivers, in fact. However, Aero is a mid-range producer. Ballistic Advantage makes Aero's barrels. I've also got several BA barrels. They're also a mid-range product. Aero bought BA a few years back.
