Have you researched the 6.8 SPC? This is a good read on how the .300 BLK, 6.8 SPC, and 7.62 x 40 match up on an AR platform.
.300 vs 6.8 vs 7.62x40 - M4Carbine.net Forums
That would be an LR-308, a little different from the AR10.I have a DPMS AR10 and have zero issues with it.
I use mine to make holes in paper and shoot hogs from a blind.
If I were counting on it to save my life while crawling through the sand box, I might be able to justify "saving my money for DPMS x2 or 3".
