Gun

The 30 mm Gatling gun mount designated as H/PJ-12 is extremely similar to the General Electric GAU-8/A Avenger. Although there are sources claiming that it is the Chinese version of the Russian Gryazev-Shipunov GSh-6-30 Gatling gun, this appears to be unlikely, since the Russian Gatling gun only has six barrels. H/PJ-12 is versatile in that its FCS system can be either separately installed at different locations like the Soviet AK-630, or directly integrated on the gun mount like most western equivalents. Like the American GAU-8/A Avenger, it is recommended not to fire longer than a single minute at a rate of 4,200 rounds per minute, after which the generated heat would begin melting the rifles of the barrel, shortening its useful life. Rates of fire beyond 4,200 rounds per minutes increase wear. There are two ammunition drums each contains 250 rounds, and other versions of the ammunition drums have been reportedly developed.
