-Would have to be fired in a AR-10 (much heavier than an AR-15) or another battle rifle already chambered in .308 leading to either a weight or versatily issue in comparison to the AR-15.
Doesn't DPMS make an AR-15 based .243?

It would be an AR-10. A .308 case will fit in a AR-15 magazine with about 1/4" to spare,the AR-15 just isn't long enough for a .308 parent case.

FWIW though, you can buy a .50 BMG upper for an AR-15, though the rifle would be a single shot.

Sure looks like an AR15 to me.

Its an AR-10, looks pretty much the same as an AR-15, but look close at the mag area, the AR-10 is longer so you can fit longer cartridges. A side by side image you can tell a lot easier.
