I was issued an M14 in the USMC in 1969 for boot camp. In those days, none of these was equipped with firing pins until we got to the Edson Rifle Range for qualification and they were removed again when we were done. The biggest thing I remember about the M14 is how heavy that critter gets when you are holding it at arm's length on the backs of your hands. We did that a lot. I remember once also when we were doing rapid assembly, I pinched my hand badly when installing the trigger group and I had to hold the assembly in while dripping blood because i didn't want the drill instructor to see this. Luckily, I got away with it and assembled the rifle when we got back to the half a tomato can (barracks). Shooting this rifle was pure joy. I sure would like to own an M1A today.
