Designed as a close-range defense weapon for trench fighting, the M1 Carbine has been used by militaries around the world. The M1 Carbine uses a bolt system that is very similar to that of the standard M1 rifle and a lightweight tappet-and-slide gas system. During World War II, many outside companies were contracted to produce M1's for the US government, including National Postal Meter, a supplier of machines for the US Postal Service. This carbine has been reworked by Arsenal with a laquered stock and the barrel has been marked "Underwood 8-43" with a flaming bomb proof. The rifle has a fixed blade front sight and no rear sight. Its wood is in fair condition and its metal and bore are in good condition.
