was upgraded to full automatic by Pearl Manufacturing. Armalite’s follow-up to the AR-15, the AR-18/180 failed to gain deep market penetration,
though many of the features (piston drive operation, ambidextrous fire controls, and a folding stock) would become popular upgrades to the AR-15
in later years. Adjustable post front and two-leaf peep rear sights, with a three prong flash hider and British commercial proofs on the barrel, ribbed
and ventilated handguard, integral scope block on the AR-180/Sterling marked upper receiver, and the Pearl “PMC” mark on the left side of the lower
receiver. The selector stops on the lower position have been cut down and rewelded to permit three-position operation, with “AUTO” added to the appropriate area, the interior of the upper receiver has been cut and reshaped to
house the safety sear, and the bolt carrier has been altered to interface
with the sear. Fitted with a smooth pistol
grip and a side folding buttstock with
ribbed buttplate. Magazine absent.
CONDITION: Very fine as converted and refinished, with 90% of the
current black and blue finish, showing a rougher texture to the lower
receiver, scattered light scratching and handling marks, and a bright, strong blue on the barrel. Mild pitting is present on the
charging handle, and the retention stud for the folding stock has been broken off (but is included with the lot). The furniture is very
good, with a number of light scuffs and dents. 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 478.
