Manufactured by the Buffalo Arms Corporation, the M2 .30 Cal saw use during World War II as aircraft armament for both fixed wing and flexible mounts, such as the rear guns on the Douglas Dauntless dive bomber and the PBY Catalina flying boat. It also earned fame in its unofficial squad automatic weapon variant on Iwo Jima, where the Marines had a limited number of M2s customized for ground fighting, known as "The Stinger". A Browning MG variant, the M2 .30 Cal essentially back-ported some of the features implemented on the .50 BMG M2 to the smaller form factor, with a significant rate of fire, reversible feed, and multiple trigger options. No fixed sights, with a ventilated heat shield, left-handed feed configuration, and the maker's markings and nomenclature on the right sideplate. A long cocking handle is fitted to the right side, with a pair of smooth "spade" grips and a knurled thumb trigger. A tripod and T&E mechanism are included.
