Could anyone point me to some books, articles, websites, etc., covering the development of the Chain gun mechanism for automatic fire?
I've taken an interest in the Chain Gun mechanism after studying a disassembled Mk44 Bushmaster. The mechanism is deceivingly simple and marked a genuinely new approach to automatic fire for medium caliber machine guns. Before the advent of the Chain Gun most other machine guns were, in essence, variations of other modes of automatic firing. Be it the Gatling-type canons, revolver canons, gas operated canons, recoil-operated etc.
I've learned that the mechanism was developed in the early seventies by the Hughes Tooling Company as a private venture and scored very high on reliability-test by, among others, the USN. It was conceived as a coaxial machine gun for the M60, first adopted as the armament of the AH-64 Apache, later selected to arm the Bradley IFV and, as a coaxial machine gun, both the M1 and Challenger 2 MBT's.
However I would like to find more details since I'm considering writing an article/essay on the weapon. That is why I'm interested in finding more information on it's development, particularly regarding it's selection as the main gun of the Bradley IFV.
Don't know if it helps, but I once watched a video called "Machine Gun Magic" made by the Dillon family of "Dillon Precision". In it they had a small piece on McDonnell Douglas and the origin of the "their" chain gun unsure if this was the true origin
