Manufactured for the Mexican Police Force with most of the examples either never being delivered or returned and subsequently sold commercially. Marked with the seal of Mexico over "S.D.N. MEXICO D.F." on the right of the magazine well, with standard Colt markings and "M4 CARBINE" nomenclature on the left. It shows standard features along with Magpul MOE pistol grip and adjustable stock, MBUS rear sight, and Knight's Armament handguard. Includes the original matching box, an extra Magpul magazine, nylon web sling, manual, and cleaning tools.

Excellent overall, retains 99% plus original black finish with some scattered light handling marks/scratches. Mechanically excellent. Box is fine with some wear and tear.
