The three forms of the .308 AR design, the Bushmaster, the Armalite AR 10 and the Knight's Armament SR 25 each use their own unique magazines - none are interchangeable. The Bushmaster is probably the most useful with regard to mags using the FN FAL units which are cheap and plentiful.

Thanks, I'll stick to the M1A, since it uses M14 mags as well. My next rifle is this: SOCOM16
