The M1A is 1930's technology. While is a darn good iron-sighted rifle, for all practical purposes, it's limited to a daytime role where those irons can be used correctly. It is a LOUSY platform for optics and lights, as well as for accuracy. Yes, an M1A can be made very accurate, but at *substantial* expense, and not without extensive maintenance. This is why the the Marines have given up on converting M14s into a "Designated Marksman's Rifle."
