What do you want your gun to do?
Given the length of action required, you really are limited to AR-10 type designs. Which fall into 2 + 1 build architectures. Which, with a very broad brush are ArmaLite and DPMS (the third are the complete AR-10 builds from Brownells, which tend to true to the Stoner designs).
If I were in the market, I like the Portuguese--pattern AR-10 (other than how hot the charging handle gets). I've just not gotten enough practice in with a T-shaped charging handle on a .308 sized AR to really cotton to any of them.
Either a Craddock turned Bartlein barrel, or Proof Research are the two LFAR barrels I would buy today.
@Varminterror Thanks for the input...although I’m not sure I would say a $200 difference (and an 80% increase) is exactly “the same price”.
I’m looking for something that will send .308 bullets down range (probably inside 300 yds) with reasonable accuracy. Not match grade accuracy...just average for an average shooter.
What’s more, is using a high end, match grade barrel WITHOUT all the supporting factors, i.e., match grade & headspace bolt, custom loaded ammunition etc., will give no better accuracy than using a Criterion, Ballistic Advantage, Faxon...probably even a stock DPMS barrel.
I call that “Inarticulate YouTubery”. Which is also clearly different than Real Life.We call this EVIDENCE.
I’d you are looking for a good complete upper, I can tell you these are pretty accurate:
