I have a Precision Firearms barrel (Criterion) on my 6mm ARC AR. Barrel care & break-in instructions that came with the barrel say to not use Tubb final finish in their barrels or any other abrasive compounds. No moly coated bullets either during break-in.
I have used Tubb's final finish before in my Howa M1500 .308 Win & my Savage M10 .223 Rem with good results. Accuracy improved enough to tell the difference & copper fouling seems to clean-up quicker. It works OK, I guess, but might not be needed for new hand-lapped barrels.
