Manufactured in the 1970s and 1980s, the "9 million" serial range M16s were intended for commercial or export sale, but made to the same military-grade specifications as Colt's domestic armed forces contracts. Features winged post front sight, A2 bird cage flash hider on the "C MP/5.56 NATO 1/7" marked barrel, "C" and "AF" marked A4 pattern upper receiver with M4 feed ramps, "C" marked bolt carrier, "MPXC" marked bolt, BCM Gunfighter Mod 3 charging handle, six-position buffer tube, and one-piece buffer. The lower receiver features the "Rampant Colt" and model markings on the left side of the magazine well and a right-handed, three-position selector marked "SAFE/SEMI/AUTO." Fitted with a ribbed handguard, A2 checkered pistol grip, and Rock River Arms telescoping stock. Includes an EoTech green dot and magnifier combo, as well as a detachable carry handle.

Excellent, with 98% of the original matte black finish, showing some light scratches and handling marks overall. The added non-Colt furniture is in equal condition, and the sight combo is in very good order (battery not included). The bolt catch has been trimmed down, otherwise mechanically excellent. NOTE: This weapon is a National Firearms Act (NFA), fully transferable Class 3, which is registered with the Bureau of Alcohol, Tobacco, Firearms and Explosives, (BATFE) under the provisions of 18 U.S.C. Chapter 44 and 27 CFR part 479.
