" I could take out an RPG team at 750 yards with an M85. Wonder why they didn't."
I reckon that they've got the bugs out of the M 85s by now. I seem to remember there was a lot of problems with them in the early 70s.
I don't think anybody uses M85's anymore. Probably can't even get linked ammo belts for it anymore. Too bad. You could fabricate a pretty nifty twin .50 mount for a gun truck with a welder and two M85's.
