Caliber 7.62 mm NATO. Max Effective Range 1100 Meters (1,200 yds). Max Range 3725 Meters (4,075 yds). Muzzle Velocity 853 m/s (2,800 fps). The 7.62mm NATO Mk43 General Purpose Machine Gun (GPMG) features the latest improvements to the M60 Series Machine Guns. It is a gas-operated, disintegrating-link, belt-fed, air-cooled machine gun. It fires from an open bolt and features a quick-change barrel. The Mk43 Mod 1 features a machined aluminum feed cover with an integrated M1913 Picatinny rail for mounting optics. An aluminum M1913 rail handguard affords mounting of infrared laser aiming devices and other sensors, giving the weapon 24-hour capability. The Mk43 Mod 0 features an injection-molded, composite handguard and typically is used as an infantry machine gun. Key Features: Reliable and user friendly. Light and compact design provides increased mobility and allows for accurate offhand (shouldered), direct fire support. Multiple M1913 rail mounting points for mounting optics, aiming lasers and accessories. Stellite-lined sustained fire barrels for extended barrel life, available in short, long or heavy fluted configuration for application flexibility. Controllable, yet lethal, rate of fire allows for accurate firing in offhand, kneeling and prone positions. Ambidextrous safety facilitates easy use. All major components directly interchange with other M60 configurations. Mounts directly or adapts to all standard NATO tripod and vehicle mounts. Major Improvements: Fail-safe reversible gas piston with simplified gas system. Adjustable front sight affords primary and spare barrels zeroing. Offset barrel handle provides a clear sight picture and eliminates needing a heat mitten for barrel changes. Lightweight, one hand-operated, receiver-mounted bipod eliminates bipod weight on the spare barrel. Lightweight forearm/pistol grip for improved control, with three M1913 rails for mounting aiming lasers and accessories. Hard chrome and induction hardening of the op rod tube facilitates easier cleaning and increases the service life of the receiver. M1913 rail top-cover allows for mounting optics, eliminates charging jams and improves operator safety by allowing a belt-loaded, but not charged, feature. The 30% improved belt pull increases reliability in harsh, dirty environments. Improved trigger group prevents incorrect assembly and features an ambidextrous safety and winter/NBC trigger guard. New flat spring latch on trigger assembly prevents accidental trigger assembly detachment. Receiver-mounted ammunition hanger provides a stable, secure mounting point for the ammunition pouch and isolates the feed tray to prevent accidental damage. Lightweight buttstock with hinged shoulder rest and improved buffer attachment mechanism provide fail-safe attachment of the buttstock to the receiver.
