I have one in .308. Crap p.o.s. won't stabilize anything but 125 grain bullets and believe me i'v tried every suitable .308 powder on the market as well at the BEST (BERGER MATH) bullets in 155 grain, Sierra 180's hornady 150 SST and can't get better than three inches. DPMS teels me the rifle in finicky and that's the way it goes with some rifles. I've read about every "back rifle" forum on the web and they are full of stories with problems with DPMS from lack of accuracy and jaming ( I'm speaking of the AR10 version.) I've sent if ack twice now complaining of accuracy. They tell me the rifle shoots 125 grain bullets well enough, then ask what more do I want? Well the .308 should be at it's best with 150 and heavier bullets thats why. Whats up with DPMS, the tout themselves and being the 2nd largest producers of black rifles on the planet. I guess they might be but they sure don't build a good one in .308.
