nothernug---You are correct on the C-rat can. It was either a B2 or B3 unit used for that reason. As I remember it helped to keep the belt more in line and aided in feeding the 60. Funny thing was that everybody wanted to shoot the 50s or the M79s. They thought it was to hard and complex to keep clean.When I wasn't operating the boat I put the 60 in a sling hung from a cable on the catwalk found it easier to operate in that fashion also linked as many belts as I could and put them in a minigun ammo can.Hey river raider. Is that a C-rat can attached to the receiver to prevent belt binding?
