The new model DPMS AR10s are lighter compared to the older ones. I have my eye on the G2 Hunter with a 20” barrel that weighs a tad less than 8 lbs. I have one of the older G1 .308s with a 16” barrel that weighs more than that. The same mags will work with he newer ones, so I am set in that department. I have a 300 BLK but just have not used it a lot.
Is that ar10 chanmbered 7.62× 51 ?
