I have a mossberg 590 mariner with a 20" barrel and i use for paper targets as well as trap shooting and hunting. Im wondering if its possible to thread my barrel for a full choke?? If it can be done would it be something that just about any gunsmith should be able to do?? and how much do you think it would cost?? I relealize this is not the best gun for shooting trap and hunting but its my first shotgun and i love it so if its possible to improve it i would like to. Thanks!!
