This sums it up pretty well..........I love the M14 and believe it is a great rifle.......a Battle rifle........They can be made to be very accurate, but it is not very cost effective.........
+1. Even once they are well tuned instruments, the maintenance is pretty high to keep them there.
Don't get me wrong, I have a tweaked 14 to hunt with when it snows, or is too humid to use a scope.
