@Amit: I realised that after a third look. My eyes completely skipped over the carbine section. Why they would make a separate section for carbines is baffling to me, though.

@Freelancer: They won't. The M14, also called the M21, now called the M39 (M21 with EBR), is locked in semi-auto and has been almost since the inception of the M14 platform. There are no fully automatic M14s issued in service. Besides, DICE learned with BC2 that automatic sniper rifles are a big no-no.
