AND NOW... (drumroll please).....I will enter into the competition the absolute WORST gun the Army EVER adopted. I know. I was 45B20 and I had to attempt to fix the wretched things. Every ex M-60 Tank jockey will now scream YES! at the top of his voice: The M-73 co-ax 7.62MM in the M-60 tank. It is a good thing the gun could be dismounted from the tank, because that happened a lot, as they were brought to my Small Arms van to be fixed. I knew that whenever curses could be heard, it was another tanker approaching, M-73 in hand. It was a rare M-73 that could get off a ten round burst without jamming. And when they jammed, they REALLY jammed. Often a complete disassembly was required to clear the damned thing. It got so bad, that we just exchanged guns and sent the offenders back for repair. I have never see a bigger .....never mind. The moderator deletes foul language. You know what I was about to say.
