With 168gr Nosler ammo, my DPMS GII Hunter in .308 is the most accurate semiauto I ever have shot.

The American Rifleman reviewer agrees, albeit with Black Hills ammo:
https://www.americanrifleman.org/articles/2020/2/6/review-dpms-gii-ar-308 (“The GII Hunter I tested blew me away with its accuracy. I was primarily testing that rifle for our sister publication American Hunter and didn't even plan to include it in this article, but the performance is too impressive to ignore. American Hunter uses three, three-shots groups with three different loads as a test protocol. With the Black Hills 168-gr. load, the first group measured 0.30". That was the best, but the average of three groups was 0.47". The average for all nine groups was 0.80". From an out-of-the-box AR-L shooting factory ammunition, that is very impressive accuracy.”).

That article also explains the cleverness and innovativeness of their redesign of the AR10 to make it better and about a pound lighter.
