Mk 48 machine gun
The Mark 48, or Mk 48, is a belt-fed general-purpose machine gun developed and manufactured by Fabrique Nationale Manufacturing Inc., a division of FN Herstal based in the United States, for the United States Special Operations Command (USSOCOM). It is chambered in 7.62×51mm NATO and is belt-fed by M13 disintegrating links or German DM1 non-disintegrating belts. USSOCOM has adopted the weapon and started its fielding process, beginning with special operations units. HistoryThe Mk 48 was designed in the early 2000s, following a request from United States Special Operations Command for a replacement for the M60.[1] Design
The Mk 48 Mod 0 is a gas-operated, air-cooled, fully automatic belt-fed machine gun. The design is based on an early 7.62×51mm NATO prototype of the FN Minimi, modified to be a scaled-up version of the 5.56 mm Mk 46 Mod 0. Being heavily based on the Mk 46 Mod 0, the Mk 48 Mod 0 features five MIL-STD-1913 Picatinny rails (one on top of the receiver, one on each side of the forearm/handguard, one under the handguard, and one on top of the barrel), an integral folding bipod, and a tripod-mounting lug. The weapon is fitted with the same fixed, polymer buttstock as the M249, although the metallic, collapsible buttstock from the "Para" model can be found in some models. The carrying handle, which had been removed from the Mk 46, was reintegrated on the Mk 48 to assist the replacement of hot barrels without use of other equipment, such as heat-resistant gloves; the handle can be folded down when not in use. As with the Mk 46, the Mk 48 Mod 0 does not have an M249-type magazine feed port, in order to save weight. The weapon can be fed from a loose belt, separate belt boxes, or clip-on ammunition pouches for 100 rounds. It has a cyclic rate of fire of around 650–730 rounds per minute. There is a high degree of parts commonality between the Mk48, M249 and Mk46 machine guns, which simplifies maintenance and repair. The use of M1913 "Picatinny" rails allows the fitting of various accessories from the SOPMOD kit, such as the ECOS-N (Enhanced Combat Optical Sight) red dot sight and other sighting or target-designating devices. The Mk 48 can also be fitted with a vertical foregrip for increased controllability during sustained fire. While heavier than the 5.56×45mm NATO M249 due to its larger chambering and heavier barrel, the Mk 48 Mod 0 is still 17% lighter and 8.4% shorter than the M240. The disadvantages of Mk 48 Mod 0 are that the life of the receiver is only about half of the M240B, and the effective range with accuracy are slightly lower than the M240B. The Mk 48 Mod 0 is currently in service with certain USSOCOM units, such as the U.S. Navy SEALs and Army's 75th Ranger Regiment.[2] Variants
 The Mk 48 Mod 1 is an update of the Mk 48 Mod 0, which is also made in FN-America. Like the Mod 0, it is essentially an M249 scaled up to fire the 7.62×51mm NATO round. The Mod 1 utilizes a 19.75-inch barrel, weighs in at 18.37 lb unloaded. Major changes include the use of an adjustable buttstock, modified rail interface system, removal of the original hinged heat guard in favor of M249-style ones attached to the barrel, and modified bipod mount.[5]
