AR upper in 300WSM?

[gb0399]

Would it be possible to make an upper for an AR-15 that was similar to the Beowolf but in a short Mag type round like the 300 WSM? Would it have a nitch in the market? Maybe as a big game rifle?

I think Olympic arms made/makes one

Do you meen WSSM? Two "s", as in "super short". In theroy, a .30 WSSM would be possible in an AR-15, since I know they make a .25 WSSM upper. The WSM (one "s") is to long for the AR-15. It should, however, fit into a AR-10 type action.
