Armalite Corporation Factory Original AR-18 5.56mm NATO C&R Eligible Transferable Machine


Status: In-Stock / Please Call to Purchase

This Chester County Armory listing is for an original, factory-produced, Curio-&-Relic license eligible, Armalite AR-18 5.56mm NATO transferable machine gun.

Built in limited production by Armalite, Inc. in their original Costa Mesa, CA facility, the AR-18 was developed in 1963 by Armalite’s lead designer, Arthur Miller, as a scaled down version of Eugene Stoner’s AR-16 design, that he developed prior to leaving Armalite in 1961.  Often called the “most successful failure” in the history of military small arms, the AR-18 is a magnificent functioning weapon, that through hap and circumstance, never was able to get a foothold in the world military market, even though it’s design and performance, and, more importantly, production costs where better than most offerings available at the time. This  model is an original, C&R eligible Armalite factory-built select-fire model, and is not an AR-180 conversion.

This particular transferable model is in phenomenal overall condition.  Mechanically, it is in excellent condition, with only very minor wear markings noted on the bolt, piston system, and fire controls. The barrel is bright and shiny, and the six groove rifling is extremely clean and crisp. It appears that this weapon has been used or fired very sparingly based on its fantastic, like-new physical condition.


Cosmetically, this model is also in excellent condition! The original satin gray phosphate finish is one of the nicest finished models we have ever had, with almost no handling marks noted in metalwork. The original high gloss forearm notes only minor handling marks and surface scratches and the folding stock and pistol grip are also fairly clean and smooth, with, again,  only minor handling marks and surface scratches visible. The right side of the receiver is tastefully engraved “MPD 513A” along with a corresponding “513A” next to the serial number. This was believed to have been placed by a former LE department. However, the excellent overall condition of this weapon suggests it was most likely an armory extra firearm.

This weapon will come with one 20rd original Armalite baseplate marked magazine.

This Curio-&-Relic eligible, “AUTO” marked, select-fire, fully transferable machine gun is currently on a Form 3 for easy transfer. The current NFA Form 3 lists “Armalite Corp.” as the manufacturer and “AR-18” as the model.
