I traded for this MKII RSI 243. I treated all the exterior metal with Eezox, put three coats of Spar polyurethane in stock interior areas and on the butt, polished the trigger and sear, free floated the magazine box, and mounted a Burris Signature Safari 1.75x5 with matte Ruger low rings. I have a Wolff trigger spring on the way. I plan on using a Montana sling.
