if you start out with a rifle you can order shotgun barrels for it. if you start out with a shoutgun you can not buy a rifle barrel for it. SHoNUFF take the scope off and make sure the base is super tight. you can get better groups with it. also take and put a o-ring on the screw post that holds the fore end. this will free float the barrel. ive got a handi rifle in .243 and love it. hope this helps.
