This isn't a FS thread so PM me for pricing.
That isn't a 'chain gun', chain guns only ever have a single barrel - it is in fact a gatling gun.
NB. The 'chain' of chain gun comes from the fact the loading/firing/ejection mechanism is powered by a chain drive rather than the blowback action from firing, eg. the Apache Helicopter's 30mm is a chain gun.
A common naming mistake made by numerous films & comp games etc.
