摘要：A belt-fed, gas operated automatic weapon of a type in which the gas pressuredeveloped in the bore is ported just forward of the chamber and utilized to compress asystem of opposing spring sets which in turn operate the various mechanisms involved inthe automatic or semi- automatic functioning of the weapon. Symmetrically arrangeddual power cylinders operated by the gas pressure compress all of the springs in theopposing spring sets by engagement with a sliding carriage. Bolt locking is carried out bya separate oscillating cam-operated bolt latch element cooperating with a shoulderrecess formed in the periphery of the bolt, with an arrangement for reducing the boltlocking mechanism forces during the unlocking interval. Manual actuation is enabled bymovement of a slider. The bolt is automatically latched open in some modes of
operation. A particular interlinked ammunition belt construction is disclosed to separateeach link from the belt after passing beyond the bolt.
