The USMC was the proponent agency for the A2 version upgrade.'Far as I know, the USMC recieved the A2 as general issue before the Army did. A friend who went to Paradise Island in '86 used the A2 in boot camp, while another friend, who went in the Army, was issued an A1 when he arrived at Ft. Bragg almost a year later.
The vehicle mounted grunts seem to favor a Carbine length rifle ala the M4.
