Just saw this on Fox. I love my CMMG MK3, finally a dedicated AR pattern rifle that shoots x39 reliably (hopefully). Although for the price I'd just buy another MK3 in 308, but I'm sure the street price will be much cheaper.
Only problem I see is the receiver sets look like MK3 (308) receivers, was really hoping for an AR15 platform not a LR308 platform. Too big for a x39 rifle. LINK
