M16 Carbine (AKA: CAR-15) In the early 1970s, Colt began development of an M16 carbine with a 14.5-inch (370 mm) long pencil barrel. The barrel length was compatible with the existing carbine-length gas system and allowed for the mounting of a standard M16 bayonet.
Despite having a longer barrel, it's no longer than the Colt Commando, as the longer barrel did not require the long 4.5 inch moderator of the XM177 series, only the much shorter M16 birdcage-type flash hider. Colt labelled the M16 carbines the Model 651, 652, 653, or 654, depending on whether or not it had a fixed or retractable buttstock, or a forward assist.
Only the Model 653 M16A1 carbine, with retractable buttstock and forward assist would be purchased in significant numbers by the U.S. military.
The Malaysian Armed Forces and the Armed Forces of the Philippines, purchased Model 653s in small numbers for special operations forces or security forces.
