I had an M-1A from Springfield Armory Inc. It was a nice rifle, but far too heavy for anything but the range. You wouldn't want to carry one up a mountain or even for across flat country for any distance.
I sold it and bought an AR-10. Never looked back. Lighter, better ergos and more accurate.
And I looked, and behold a pale horse: and his name that sat on him was Death, and Hell followed with him. And power was given unto them over the fourth part of the earth, to kill with sword, and with hunger, and with death, and with the beasts of the earth.
