Produced by Inland (General Motors), the largest M1 Carbine contractor, this rifle aligns with late-1944 production features. The 12-44 barrel date and Inland/GM rollmark are clear, and the receiver carries the standard "U.S. CARBINE / CAL. .30 M1" legend.
It uses the short-stroke gas piston, semi-automatic action with an 18-inch barrel and a GI-pattern detachable box magazine system. Capacity is 15+1 with the included 15-round magazine.
Sighting equipment consists of a protected blade front and a stamped, fully adjustable aperture rear sight with a windage knob. The rifle retains the narrow barrel band without a bayonet lug and a round bolt, both characteristic of its late-war feature set. The gas piston housing is located under the barrel.
The hardwood stock has an oil finish, straight grip, oval sling cut, and a steel buttplate, matched with a hardwood four-rivet top handguard. Notable marks include a "P" proof on the barrel behind the front sight and a boxed foreign property/rack stamp on the right buttstock (not a U.S. Ordnance acceptance mark). The receiver is steel with a phosphate finish, consistent with the listed overall phosphate finish.
