Federal law requires firearm purchases to go through an FFL dealer with a completed ATF Form 4473 and NICS background check, while ammunition sales follow standard retail procedures. Arkansas does not require a state permit to purchase ammunition, though buyers must meet federal age minimums of 18 for rifle ammunition and 21 for handgun ammunition 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. Store ammunition in a cool, dry environment away from heat sources and solvents, and keep loaded magazines separated from bulk reserves. Contact the shop directly with questions about specific Underwood loads, projectile options, or current availability.
