I got to compare my PTR91 against an original full auto HK (in 9mm though) and myself and the owner agreed that the PTR showed better workmanship.
The PTR has a better barrel than any military rifle but still, this is primarily a battle rifle not a target rifle. If you have to have match grade accuracy there are a number of 308 AR10's with match barrels and triggers.
Bill Springfield did a trigger job, and the trigger is as good as a match M1a. I am certain the prices have changed, so I X'd them out, but here is the message:
