Ken, I have 3 DPMS AR's, chambered in .223, .308 and .338 Federal.
I've actually successfully hunted with the .338 numerous times, harvesting deer and hogs. At the price you mentioned, it's probably a bare bones model, mine were built with various upgrades such as heavy barrel and trigger groups. Check with R&R Arms, that's where I ordered these 3, shipped to a local FFL dealer for transfer.
