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.

Famous quotes containing the word gun:

    What cannot stand must fall; and the measure of our sincerity and therefore of the respect of men, is the amount of health and wealth we will hazard in the defence of our right. An old farmer, my neighbor across the fence, when I ask him if he is not going to town-meeting, says: “No, ‘t is no use balloting, for it will not stay; but what you do with the gun will stay so.”
    Ralph Waldo Emerson (1803–1882)

    I grew up in a tough neighborhood and we used to say ‘you can get further with a kind word and a gun than just a kind word.’
    David Mamet, U.S. screenwriter, and Brian DePalma. Al Capone (Robert DeNiro)

    Though I had not come a-hunting, and felt some compunctions about accompanying the hunters, I wished to see a moose near at hand, and was not sorry to learn how the Indian managed to kill one. I went as reporter or chaplain to the hunters,—and the chaplain has been known to carry a gun himself.
    Henry David Thoreau (1817–1862)
