im a dept mngr for walmart sporting goods and yes the sotre has to sell firearms to have the special order book, we get a new one every year with what we are allowed to oder from sports south, we have shotguns and rifles. there is a pretty good selection to choose from, but if its not in the book we cant order it. if there is something you would like me to look up for you i would be more then happy to and even give you the price its running at that time. to get a gun for the book you must put 50% down and pay the rest when picking up and after a background check. im in the state on va so the process is different from state to state.
