Federal law requires firearm purchases to go through an FFL dealer with a completed ATF Form 4473 and NICS background check. Arkansas does not require a state permit to purchase a handgun or long gun, and there is no mandatory waiting period, though buyers must meet federal age minimums of 21 for handguns and 18 for long guns from a licensed dealer.
Arkansas is a permitless carry state, allowing eligible adults to carry concealed without a license, while the Concealed Handgun Carry License remains useful for out-of-state reciprocity. Transport firearms unloaded and cased when required, and store them securely using a safe or locking device. Contact the shop directly with questions about transfers, special orders, or current Sig Sauer inventory.
