Haven't heard much encouragement in this thread for the GSR. It's around half the price of the M1A as is the mini-14
If you are looking for a "do all" rifle, then its hard to beat the M1A with it's semi automatic operation. It provides for much faster follow up shots and it's staggered column magazines hold more ammo.
The Ruger Gunsite rifle is still a fine choice, but it's more limited in it's capabilities thanks to being a bolt action. The Ruger will be easier and cheaper to scope, as it had a picatinny rail in place for a scout scope and the rear sight can be removed to mount a tradition scope.
