Built since the 1920s, the reliable, powerful, air-cooled .50 caliber (12.7 mm) M2 Browning Machine Gun (aka. “Ma Deuce”) is still one of the world’s most effective heavy machine guns. It can be carried by a team of soldiers, or mounted on vehicles and aircraft. Despite its age, its combination of reliability, durability, and kick-butt firepower has made it one of the most requested weapons in the Iraqi theater of war, and it remains popular around the world. Modern alternatives like FN’s M3M/GAU-21 have been introduced, and the XM307/312 remains a future possibility, but the M2 remains, as one of our correspondents put it, “the mounted lance of the US cavalry.” The USA has even had to ramp up .50 cal ammunition production, in order to keep up.
This article covers the venerable, and valuable, M2 machine gun, and associated contracts. The US government is still buying more, and has just issued a multi-year contract, and a small business secondary supplier contract…

Ma Deuce: the M2 Heavy Machine Gun
(click to view full)
The M2HB crew-served 12.7mm/ .50 cal machine gun features a rate of fire of 450-600 rounds per minute, a maximum effective range of 2,000 yards (1,830m), and a maximum range of 7,440 Yards (6,800m). Muzzle velocity with M33 is 2,910 Feet Per Second (890 Meters Per Second). As has become standard in modern machine guns, it is air-cooled and belt fed. The complete gun weighs 84 pounds (38.2 kg), not counting any tripods or mounts, with a barrel weight of 24 Pounds (10.88 kg).
The M2’s slow rate of fire is not necessarily a disadvantage. Though it limits the gun’s anti-air effectiveness, it makes the weapon more controllable against ground targets – and has even led to combat situations where the M2 has been successfully employed in one-shot sniper mode using a telescopic sight. Discovery of the M2 sniper option is widely credited to legendary USMC sniper Carlos “White Feather” Hathcock in Vietnam.
The M2HB comes in 2 variants, fixed and flex. The fixed version is generally used on tanks, and has different mountings and a different trigger mechanism.

General Dynamics Armament and Technical Products has developed an M2E2 version, after 25 years of experience manufacturing the M2HB machine gun for the U.S. Department of Defense. The enhanced M2E2 provides new features and design improvements, including a quick-change barrel system that can be switched in seconds, rather than forcing gunners to adjust the headspace and timing while in combat. Other key features include a flash hider, and a manual trigger block safety. M2E2 is currently in production, but the M2 and M2HB remain the mainstays of American orders.
The Lightweight .50 Caliber (12.7mm) Machine Gun (LW50MG) is a more developmental variant. The LW50MG is expected to have significantly less recoil, and to be lighter than current weapons. It is also expected to demonstrate increased accuracy and lethality in combat, though an LW50MG that simply maintained the M2HB’s marks in those areas could still be valuable.
Secondary supplier U.S. Ordnance has also developed its own M2QCB design, alongside the M2HB. It includes additions like M1913 Picatinny Rails for mounting an array of combat optics and other gear, options that include a flash suppressor, and a trigger positive safety selector to prevent accidental discharges; and a Quick Change Barrel (QCB) that maintains fixed headspace, allowing the barrel to be safely changed in seconds.

Unless otherwise indicated, all contract are issued by the The U.S. Army Tank-Automotive and Armaments Command at Rock Island, IL to General Dynamics Armament and Technical Products Inc. in Burlington, VT.
July 15/09: Do they feel lucky? U.S. Ordnance, Inc. in Reno, NV received a $6.75 million firm-fixed-price contract for 548 M2 machine guns. That number is the exact small business set-aside difference noted in the May 9/09 entry. The Pentagon announcement noted a potential for a maximum order of 30,678, but that is only likely to happen under extreme circumstances.
Work is to be performed in Reno, NV, with an estimated completion date of Aug 31/12. The TACOM Contracting Center in Rock Island, IL solicited 6 bids, with 6 bids received (W52H09-09-D-0249).
May 8/09: General Dynamics Armament and Technical Products Inc. in Burlington, VT wins a $24.2 million 4-year firm-fixed-price indefinite-quantity/ indefinite-delivery contract, including an initial order for 2,193 M2HB Flex machine guns. This initial order is the multi-year contract’s minimum order quantity. Work is to be performed in Saco, ME, with an estimated completion date of Aug 31/12. Six bids were solicited, with 6 received by TACOM in Rock Island, IL (W52H09-09-D-0175).
The DefenseLINK release lists a potential contract maximum quantity of 39,452 guns over the 4-year period, but TACOM initial solicitation information [PDF] lists 40,000 guns. The difference is attributable to a small business set-aside, which will be issued as a follow-on contract.
Since the contract is firm-fixed-price, its maximum value to General Dynamics can be inferred as being around $435 million. TACOM personnel told DID that the contract may modified in subsequent years, however, to include the M2E2 variant. If that comes to pass, final totals may change.
April 3/09: A $29 million firm-fixed-price contract for an additional 2,414 M2HB machine guns. Work is to be performed in Saco, Maine with an estimated completion date of April 2/09. One bid was solicited and one bid was received (W52H09-07-C-125).
According to GD-ATP’s April 25/09 release, this option brings this 2007 contract’s total value to date to more than $100 million. It adds that deliveries from this award are expected to begin in December 2009, which further suggests that the DefenseLINK completion date should read April 2/10.
Oct 7/08: U.S. Ordnance of Reno, NV won a $14 million firm fixed price contract to purchase “M2HB nonstandard machines for Afghanistan.” The work is being performed at the contractor’s Reno plant and will be complete by Sept 30/09 (W52H09-08-C-0218).
One US Ordnance M2HB feature that might be very useful in Afghanistan is an optional positive safety selector for the trigger mechanism, to prevent accidental discharges when manning the gun and traveling over rough terrain. A quick-change barrel is also offered – from their site:
“US Ordnance’s most recent improvement to the time honored M2HB machine has been the addition of a quick change barrel with fixed headspace. Our innovative Quick Change Barrel (QCB) maintains fixed headspace and allows the barrel to be safely changed in seconds, allowing accurate pre-operational set-up and improving sustained fire support in battle.”

Sept 24/08: General Dynamics Armament and Technical Products Inc in Burlington, VT receives a $10 million firm-fixed-fee price contract for 829 M2HB machine guns. Deliveries on the contract are expected to begin in late 2009, and to be complete by the end of 2009.
Production work will be performed at GDATP’s Saco, Maine, facility, which has delivered more than 25,000 M2 heavy barrel machine guns to the U.S. government since 1979. Program management will be performed at the company’s Burlington, VT based Technology Center, which is GDATP’s Engineering Center of Excellence. One was solicited and one bid was received (W52H09-07-C-0125). See also General Dynamics Armament and Technical Products release.
May 14/08: GDATP announces a $9 million contract from the U.S. Army Joint Munition and Lethality Life Cycle Management Command to develop a Lightweight .50 Caliber (12.7mm) Machine Gun (LW50MG). The contract will fund development of the gun and system components such as the tripod, vehicle adapter assembly and Blank Firing Adapter (BFA).
The LW50MG is expected to have significantly less recoil, and to be lighter than current weapons. It is also expected to demonstrate increased accuracy and lethality in combat, though an LW50MG that simply maintained the M2HB’s marks in those areas could still be valuable.
Nov 26/07: A $36.6 million firm-fixed price contract to purchase 3,048 M2 machine guns for foreign military sales. The work will be carried out at the company’s Saco, Maine, facility for completion by June 30/09. Army Public Affairs can be reached at (703) 692-2000. (W52H09-07-C-0125).

Jan 18/07: GDATP announces a $6.9 million contract modification from U.S. Army TACOM in Rock Island, IL to produce M2HB Machine Guns. This option modifies a contract originally awarded in October 2006, bringing the total contract value to date to $27.5 million.
