re: #91 ckkatz
I always hated the M-60 with a passion. Heavy, unreliable, several “gotchas” in the design like the wire you mention (put the spring holding the pins for the trigger group on backwards and it’ll easily pop off leading to a run-away firing machine gun when the pins work out and the trigger group falls off). The ones I had to deal with in the 80’s & 90’s were all really badly worn out on top of it.
