I was at the CMPnorth store a while back and checked out some of the barreled receivers, but I cannot remember if the. 308 barreled receivers had any markings on the barrel or not, I would bet they probably are stamped with something though. I did check the chamber with go and no go gauges and it's good to go, and the rifle has clearly been fired, so I bought it anyway. I have lots of. 308 ammo, so I figured why not. And the cost was just too good to pass up. :-)
