notes"The MG 3 is a German general-purpose machine gun chambered for the 7.62×51mm NATO cartridge. The weapon's design is derived from the World War II-era MG 42 universal machine gun that fired the 7.92×57mm Mauser round. The MG 3 was standardized in the late 1950s and adopted into service with the newly formed Bundeswehr, where it continues to serve to this day as a squad support weapon and a vehicle-mounted machine gun. The weapon and its derivatives have also been acquired by the armed forces of over 30 countries. Production rights to the machine gun were purchased by Italy (MG 42/59), Spain, Pakistan (MG 1A3), Greece, Iran, Sudan, and Turkey. The German military instructs sustained fire must be avoided at all costs. In the bipod mounted light machine gun role MG 3 users are trained to fire short bursts of 3 to 5 rounds and strive to optimize their aim between bursts fired in succession. In the tripod-mounted medium machine gun role, MG 3 users are trained to fire short bursts and bursts of 20 to 30 rounds and strive to optimize their aim between bursts fired in succession. After around 150 rounds of rapid-fire, the gun operator will open a side hatch (leading to the barrel) and replace the hot barrel with a new cool(er) one. Non-observance of this technical limitation renders the barrel prematurely unusable. The machine gun crew member responsible for a hot barrel change is issued protective asbestos gloves or a cloth to prevent burns to the hands. The MG 3 is an automatic, air-cooled, belt-fed short recoil-operated firearm. It features a roller-locked bolt mechanism that consists of the bolt head, a pair of rollers, the striker sleeve, bolt body, and returns spring. The bolt is locked securely by a wedge-shaped striker sleeve, which forces two cylindrical rollers contained in the bolt head outward, and into corresponding recesses in the extension of the breach of the barrel. On firing, both the barrel and barrel extension recoil to the rear. The resulting impact (much like Newton's cradle) moves the carrier to the rear withdrawing the wedge and both rollers as they are cammed inward and out of their sockets by fixed cams, unlocking the bolt head. The bolt carrier and bolt then continue to the rear together guided by fixed guides while the barrel and barrel extension return to the battery. Upon return of the bolt forward, the impact of the rollers against the camming surfaces on the breach carries the rollers from their seats, and, together with the surfaces on the striker sleeve, force the rollers outward, locking the bolt head into the barrel extension and ensuring a complete lock. The bolt also houses a spring-loaded casing extractor and ejector. Ejection is carried out when the ejector strikes the buffer head, sending a push forward through the ejector bar, which hits the ejector pin. This pin pushes the top of the base of the cartridge, which is still held by the extractor at the base, causing the empty casing to rotate and eject downward through the ejection chute. The machine gun has an automatic-only trigger mechanism and a cross-bolt safety in the form of a button that is operated by the shooting hand (in its "safe" position the bolt release is disabled). The weapon fires from an open bolt. The cyclic rate can be altered by installing different bolts and recoil springs. A heavier bolt uses more recoil energy to overcome inertia, thus slowing the action. On MG 3 machine guns, two types of bolts are available, with standard weight (about 650 g (22.93 oz)) for the standard 1,000–1,300 rounds per minute cyclic rate of fire and with extra weight (about 900 g (31.75 oz)) for a slower 800–950 rounds per minute cyclic rate of fire. Those bolts also are used along with different return springs. The MG 3 feeds from the left side through a feed block using metal, 50-round continuous-link Patronengurt DM1 ammunition belts (which can be combined by cartridge) or disintegrating-link M13 or DM6 belts. In the light machine gun role, the MG 3 is deployed with a 100-round (or 120-round in case of disintegrating belts) belt fitted inside a synthetic ammunition drum developed by Heckler & Koch that is latched on to the left side of the receiver. The rear wall of the drum is transparent and serves as a visual indicator for the amount of ammunition available. The feed system operates through a feed arm that is housed in the feed cover. Two feed pawls are linked to the front end of the arm by an intermediate link and move in opposite directions, moving the belt in two stages as the bolt moves back and forward during firing. For the light machine gun role, the MG3 is equipped with a synthetic polymer stock and a folding bipod."
