Basic Information
The weapon is essentially based off of the MG3, with a number of cosmetic changes and changes in material composition, and modified firing system. The weapon sports a polygonal 5 groove 1: 10 inch (254mm) right hand turn cobalt-alloy "flow formed" barrel; the barrel is made of an alloy that contains more than 50 percent cobalt. The barrel is roughly 13% heavier than standard steel barrels, but is more erosion and corrosion-resistant and is designed to retain high strength during long-term exposure to high temperatures. Cobalt alloys are frequently used in the aerospace industry, such as the hot-gas section of turbine engines. A proof of concept M240 7.62mm x 51mm NATO barrel, in practice, had 24,000 rounds test-fired through it, causing it to reach temperatures of 1,100 degrees, without failure. A steel barrel would have failed under such treatment.
The weapon uses mostly flow formed cobalt alloy for the rollers and the firing mechanism, although steel parts are present similar to both the G3 and MG42. In addition, the weapon uses advanced caseless .30-06 rounds, which are more powerful than the rounds from either the MG42 or MG3, and also lighter weight. The weapon is capable of firing multiple types of rounds, although to stabilize tracers the weapon requires a specially designed barrel with appropriate rifling, that reduces the accuracy somewhat to around 2-3 MOA.
Other than the firing system and rail attachments, the weapon remains nearly exactly identical to the MG3 and MG42 styled weapons.
