My 7.62/.308 DPMS GII Hunter with a 20” barrel weighs only 7-lbs 12-ozs—before adding scope/mounts or anything else.
From the American Rifleman:
“The GII is smaller and lighter, almost as small and as light as the AR-15 rifle. Current models start at 6 lbs., 14 ozs. Ballard said, "Depending on the model, the GII can weigh from one to several pounds less than its older LR counterpart." To accomplish that weight reduction, the engineers had to create new upper and lower receivers, as well as a new bolt carrier. … The forged, monolithic bolt carrier in the GII is another redesign from the old style. It eliminates the larger forward section and is the same size for its entire length. The new bolt carrier measures 0.930" at its largest point as opposed to the previous design at 1.135". The new bolt carrier is also 0.6" shorter than its predecessor. The GII bolt carrier group weighs 6 ozs. less than the old style. … The GII bolt uses new geometry for the locking lugs where every edge has a radius to enhance reliability. There are two ejectors rather than the standard single. Ballard said that is to help reduce spring fatigue. Of course, it also introduces redundancy as the gun will operate with one ejector. ...
This 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.”
https://www.americanrifleman.org/articles/2015/1/5/downsizing-dpms-gii-ars/I also get an average of around 1/2” 100-yd groups with Nosler factory 168-gr ABLR loads.
Even with the reduced overall weight, it has a fairly-heavy/thick barrel that seems to absorb more heat than most ARs.
So far, I’ve only shot a few deer with it:
But it’s a great fairly-lightweight .308 AR. It is more accurate than any other AR I have shot, and it has never failed to fire (except when my son tried Hornady reduced-recoil ammo through it—not enough powder).
