In 1967, Colt replaced the CMG-1 with the CMG-2. The CMG-2 abandoned any commonality with the M16 and was only available as a bipod-mounted light machine gun with a vertical foregrip. It was fed from a 150-round belt using S-63 link contained in a drum. The CMG-2 was gas-piston operated, but used an M16 bolt. The extractor was machined into the bolt. The CMG-2's barrel was detachable and had a handle, so an overheated barrel could be replaced in the field. The barrel had a 1:9 twist and was meant to fire an experimental 68-grain (4.4 g) bullet, designed for longer ranges than the then-standard 55-grain (3.6 g) M193 bullet. Unlike the M60 machine gun, then in use in the Vietnam War, an M2 bipod was mounted on the CMG-2's ventilated handguard. The most unusual feature was that a user charged the CMG-2 by unlocking the pistol grip, and then sliding it forward and back. Colt submitted a buttstock-less short-barreled CMG-2 to the Navy SEALs. The Navy classified the CMG-2 as the EX 27 Mod 0 machine gun but they ultimately chose the Stoner 63 MK23 Mod 0 Commando instead. The CMG-2 never left prototype phase and Colt ceased development in 1969.
