from what I remember when doing research previously, cost was a hugge prohibitive factor, and the size seemed rather cumbersome. My immediate thought was that a .308 AR 1o style rifle could do JUST ABOUT everything a 06 version could, and do so at a MUCH lower cost all the way around.

Hope you're proud of yourself.
