The Commando Mark 45 operates on a simple, reliable straight-blowback action and is hammer-fired for consistent ignition. A right-side charging knob and fixed cross-bolt safety provide familiar controls.
The 16-inch barrel is surrounded by a steel, finned heat-shield that aids cooling and evokes the look of the wartime Thompson SMG. A slotted muzzle brake further enhances its iconic profile while helping to tame muzzle rise.
The cast-alloy lower mates to a robust square steel upper receiver finished in black oxide. Combined with the hardwood stock and sling swivel, the rifle offers durability and classic lines suited to both range use and display.
Patent number 3,695,143—credited to Melvin M. Johnson Jr.—is stamped on the receiver, adding an interesting historical link for enthusiasts. Serial number 63613 places this example within the desirable open-bolt production era.
Chambered in .45 ACP and feeding from common 30-round M3 magazines, the Commando Mark 45 delivers hard-hitting performance with affordable, widely available ammunition.
