Colt M16 Light Machine Gun (LMG) 5.56mm NATO Factory Experimental Transferable Machine Gun


Status: In-Stock / Please Call to Purchase

This Chester County Armory listing is for a very rare, factory experimental version Colt M16 LMG 5.56mm transferable light machine gun.

Early creation of this model, and its use at Colt, lead directly to the creation of the LMG’s standard production model. This fully transferable machine gun features an extremely rare “X” marked serial number, added L.M.G. markings from Colt to a M16 receiver. and operates using an open bolt system, just as later LMG production models did.

It also features an early version of the elongated handguard, a rare, angled style foregrip from a CMG-2 (that was later replaced with a vertical foregrip), and a bipod adapted from an M60 machine gun, instead of the production versions found on later models.  The lower receiver is marked Colt Firearms Division, Colt Industries.

This extremely rare, experimental version of the Colt LMG is fully transferable and currently on a Form 3.
