MK I's were a sound way to fly,prior to the advent of S/S OEM rifles. Had piles of 'em and never puked one mechanically,save bottom metal. Had lotsa stocks walk,their bottom metal was absolute dogschit and it takes more than an adjustable trigger to piss me off. Rebarreled more than a few with High Zoot S/S spouts and poked good stocks on 'em,but the perpetual Ruger bane is their weight and arranging max erector travel.
Good talk.
