Since they are all mil spec and CNCd, is it primarily the barrel? Assuming the shooter is capable and has a good trigger installed, can you buy sub moa with just a barrel swap?

Good barrel is the place to put your money. Geissele triggers help a lot too due to fast lock time. While national match BCG and adjustable gas block are not absolutely necessary I think they area good idea on a precision build. As for assembly, there are some tricks to ensure your gun has the best chance to shoot well.

Thanks. I just received my Larue MBT2S that will be installed soon. Plan to see what that does for accuracy.
Can you elaborate on the assembly tricks?

Your question is one that has been asked forever with no definite answer. But I would agree with the barrel first. I've built many.
A test I tried was with a 6.5 Grendel I built
Seekins upper and lower.
Velocity 3lb single stage trigger
WMD BC
Satern cut rifled barrel w matching type II bolt.
Shot factory Hornady 123 sst.
Sub moa. Repeatedly. Not just one outing.
Changed the lower and upper to a Anderson. Used all the other parts.
Groups remained the same.
Used a 80% lower and a ATI polymer upper. Used all the same parts again.
Groups remained the same.
Laborious but proved to me.
I made a HBAR with a $89 5.56 barrel. No special parts. Anderson mil spec lower parts. AIM BCG I can count on it for MOA group.
My ID pic is my 6.5 Grendel.

BTW check out Velocity triggers. I own Geissle triggers on the high end. Won't be buying anymore of them..

As for assembly, there are some tricks to ensure your gun has the best chance to shoot well. This is the advice I'd give you as well, the only thing I would add is shoot quality ammo or reloads. Don't buy 55 gr. Full metal jacket rounds on discount and expect .5@100 accuracy. If you handload there are proven loads that shoot in any well built gun with a decent barrel and trigger. Black Hills makes really good factory ammo. |

I shoot 2 stage at work and I try to keep everything the same as what I always use but the HyperFire is the way is go if I was using one for 3Gun. |

So barrel, chrome lined, steel or melanite? Melanite seems to combine the best of both worlds, reasonably priced too. What twist? 5.56 or wylde chamber?

Not sure what you want to spend on a barrel or what you how you define accuracy. The last 2 barrels I have purchased have been Criterion and the inside finish and accuracy are excellent. They shoot well and clean up fast. Ballpark $300. I have a Wilson barrel ( factory on Rock River) shoots pretty well and it's probably a $200 barrel. Like most things in life you get what you pay for--never more and sometimes less.
Barrels listed are all stainless steel, button rifled. Josh at Criterion says he's hearing good things about their chrome lined barrels but I have no further knowledge. You'll likely not wear a barrel out stainless, moly or lined.

Melonite is snake oil as far as barrels are concerned. It might help a 223 go a little while longer buti know for a fact it won't extend the life ofa fast 6.5mm or 7mm. I don't like it on stainless either if it's a pressure vessel. Awesome for CM bolts, pistol slides, etc.
Criterion, WOA, Ranier, CLE, etc are all solid buys.
