I have read Faxon recently had to switch the company that did their QPQ because of issues. Rough bores etc and some other people have reported similar issues as yours. Ask to speak with Pat at Faxon and ask for a new barrel.
If that doesn't work out for some reason, as Stick mentioned the Rainer barrels are good stuff. I believe they recently switched it the blank manufacturer for their ultramatch barrels. A member on the hide PADOM I believe had a thread in the semi-auto section testing a few different calibers. Intial results look very good.
I am not sure if your requirement is still for a pencil barrel, but groups will open up after some rounds no matter what due to the profile. Maybe try to have it replaced out for their Gunner barrel which has a little weight towards the chamber and pencil past gas block.
Ballistic advantage Hanson would be my pick on the value end. I would also look into:
Larue Predator or stealth barrels
White oak
Keystone Accuracy
Compass Lake
They all make high quality match grade barrels and would probably work for you if you are willing to compromise on the pencil profile. Even BA has an MOA guarantee.
