Item Description

This Chester County Armory listing is for a factory original Colt M16 Model 613 5.56mm NATO transferable machine gun.

The Colt Model 613 was originally offered by Colt as a Commercial Sales version of the venerable military-provided M16A1 from 1973-1982 after demand for Colt’s military version declined following the end of the United States’ involvement in the the Vietnam War.  Built as a 20″ barreled standard rifle M16A1 variant with a teardrop forward assist, the 613’s were typically “AR-15” marked for civilian sales, but often “M16” marked for direct sales to law enforcement agencies. This particular model does indeed have the much more rare and desirable M16 markings. These models were typically offered in the 5,000,000 serial number range, and this model is no exception. Production of this weapon by Colt appears to be in early 1974 based on its serial number.

This beautiful transferable Colt factory machine gun has had its original A1 furniture upgraded to Colt’s A2 furniture that was first produced in 1982. The remainder of this transferable machine gun remains in its original configuration, including a 1/12 twist original chrome-lined barrel, and it’s original “C” marked BCG. It also features the desired “SAFE”, “SEMI”, and “AUTO” fire control markings. Mechanically, this model is in excellent overall condition. The original fire control internals note very little wear markings. The sear and disconnector are clean with crisp edges; the hammer notes only limited surface markings, and the BCG displays only minor wear.  The barrel rifling also remains crisp and clean, with well-defined lands and grooves.

Cosmetically, this almost 50 year old machine gun is also in overall excellent condition. There are some minor handling and surface scratches on the exterior original phosphate finish and some small surface scratches in the polymer furniture, but no dents, dings, gouges, or malformations are observed in the metalwork or the furniture that would create a cause for any concern.  The right side of the receiver by the fire controls is marked with 3 small initials and a number, which was made by the original LE agency that first purchased this weapon from Colt.

This factory original Colt M16A1 transferable machine gun is currently on a Form 3 for easy transfer. The NFA paperwork indicates the manufacturer of this weapon as “Colt” and the model as “613”.
