Nothing gets our juices flowing quite like a Ma Deuce, so when we heard the U.S. Marine Corps announced last year that it would field the M2A1—an updated version of that iconic .50 BMG heavy machine gun—we were understandably excited.
The M2A1, around 3,600 were fielded by the USMC in FY18, is known for three key features that the service says make it safer and easier for marines to use: a quick-change barrel; fixed headspace and timing; and a flash hider that reduces the weapon’s signature by 95 percent at night. In addition, this belt-fed, recoil-operated, air-cooled, crew-served fighter weighs in at 128 pounds with a tripod, with a cyclic rate of fire of 450 to 600 rounds per minute. Meanwhile, its maximum effective range is around 2,000 yards, or 1,830 meters.
If you’re curious about the inner workings of this weapon, you’re in luck: in the video above, a Marine walks you through how to assemble and disassemble the M2A1.
