"ROCK-OLA" marked barrel, "MMQ" marked type 3 barrel band, "I.R.CO." marked rear sight. Fitted with an unmarked M2 'pot-belly' stock. Includes a "US M4/KI" marked bayonet, M8A1 scabbard, an extra rear sight assembly, and a spare pistol screw.

Fine as arsenal refurbished, with some scattered pitting, light spotting/freckling, light cycling wear, edge wear, and mild handling wear. The stock is also fine as sanded and re-oiled.

"I.B.M. CORP." marked barrel, "AO" marked Auto Ordnance sub-contracted receiver, "EPB" safety, "LW-B" stock. Includes a web sling and oiler.

Very good as arsenal refurbished, with arsenal restamped digits in the serial number, some minor freckling/spotting, brown patina, dried grease, and mild handling wear. The stock is also very good as sanded with a brass pin repaired crack running through the forearm. Mechanically excellent.
