I'm a newbie here. So go easy on me. I've been shooting sporting clays and working my way up to Master the last 7 or 8 years and now I'm looking for something new and 3 gun competitions have peaked my curiosity. I have shotguns figured out for now and I have a 9mm comp pistol that I can use but I know nothing about rifles. What would you say is the best S & W AR for 3 gun competitions and why?
