Colt M16A1 Selective Fire Rifle, Nine Million Serial Range, Class III/NFA Fully Transferable Machine Gun

Manufactured during the 1970s and 1980s, this Colt “9 million” serial range M16 is a highly desirable collector-grade example from a distinctive production category intended for commercial or export sale while still built to the same military-grade specifications as Colt’s domestic armed forces contract rifles. It retains the classic Vietnam-era A1 configuration that collectors prize, including a winged post front sight, A1-style flash hider on the “C MP CHROME BORE” marked barrel, bayonet lug, triangular handguard, and an “L M” marked upper receiver with a two-leaf windage-adjustable rear sight, fixed carry handle, short casing deflector, and teardrop forward assist. The lower receiver displays the standard markings on the left side and is fitted with a right-handed selector marked “SAFE/SEMI/AUTO,” an A1-pattern pistol grip, fixed A1-pattern buttstock, and black nylon sling. Internally, it features a matte black finished bolt head and carrier, with the bolt head marked “MPC” and the carrier marked “C” and serrated for the forward assist, along with a one-piece buffer, “7” and “C” marked hammer, and proper safe/semi/full internals. Also included is a “U.S. M7” marked bayonet, without scabbard, adding further period-correct appeal. With its sought-after Colt manufacture, military-grade construction, iconic A1 features, commercial/export “9 million” serial range distinction, and desirable included bayonet, this M16 stands out as an important and investment-worthy piece for advanced Colt, U.S. military, and Class III collectors.
