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 it's 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. This example was registered with the ATF as a Deactivated War Trophy (DEWAT); the internal parts have been removed, the sideplates and trunnion show cracks and deformation, and the underside of the chamber and the sideplates at the feed mechanism have been cut through with a torch. A pair of metal bars have been welded to the sideplates to hold the receiver together for display. Fitted with a ventilated heat shield and a custom manual trigger, and installed on a custom metal display stand.

Fair as deactivated (see above), with 40% of the original finish, showing spotting and wear overall. NOTE: This is a registered DEWAT weapon with the Bureau of Alcohol, Tobacco Firearms and Explosives (BATFE), as a National Firearms Act (NFA) weapon, that is fully transferable. It has been classified as a Curio or Relic as defined in 27 CFR, 478.11. These weapons are still subject to the provisions of 18 U.S.C. Chapter 44 and 27 CFR part 478.
