Yeah, I bought a DPMS 308 a while back to go along with my AR15. I absolutely LOVE the 7.62 platform. DPMS gets a bad rap but I don't really understand why. Mine (the AR10) so far, is accurate as hell out to 800 yards with a good scope. Just be careful with your new gun. Don't be one of "those" guys with 18 pounds of crap on yours.
Also, Palmetto State is a good place for parts should you need them.
