This example is an early Powder Springs gun manufactured in 1971–1972, prior to the 1986 U.S. machine gun ban. The receiver is marked "INGRAM M10, CAL 9MM PAR / MILITARY ARMAMENT CORP / POWDER SPRINGS, GA, USA" and carries the Cobray snake logo, with selector markings SAFE/FIRE on the left side and SEMI on the right.
It operates via an open-bolt blowback system with a selective-fire selector and a push-button safety. The charging system uses a top-mounted, knurled, reciprocating knob with a longitudinal slot. The upper receiver features two longitudinal strengthening ribs, and the overall construction is stamped and welded steel.
The barrel measures 5.75 inches and is threaded. The fixed hardwood shoulder stock provides a length of pull of 15.5 inches and includes a rear sling swivel, with sling provisions front and rear. A polymer pistol grip completes the control layout.
Included support gear adds utility and historical appeal: an RPB Industries M10/9 suppressor, three 36-round sheet-metal stick magazines with witness numerals, a sheet-metal magazine loading tool, a green web front hand strap attached to the front sling loop, and a soft black carry bag.
Chambered in 9mm Luger with a 36+1 capacity, this M10/9 brings together classic MAC features and correct period markings, along with a matching platform suppressor and useful accessories.
