RE: Ruger??
My brother had one, you could pull the trigger as fast as you could and shoot a paper plate size group, when he put a scope on it, it still shot a paper plate size group. My friend barrowed his cousins for a winter and that one shot about a 1.5" group with a scope. I don't think they are worth the 5-600 they want for them. I would personally buy the Armalite AR 15, it is closer to the M16 than the mini 14.
