Franklin ArmoryA(R) is proud to produce 100% American made quality firearms. The ReformationA(R) RS7 is built with many of the custom features ready to go right out of the box. From the awesome TriumvirA(R) flash hider to the Custom Tuned trigger to the B5 Systems Bravo Stock we know you will appreciate the quality and pricing this model affords. Featuring the straight cut land and groove design of Franklin Armory's patented NRS(TM) (Not a Rifle or Shotgun) barrel technology the 7.5-inch Reformation configuration is classified as neither a rifle nor a shotgun. Rather Reformation is simply a "firearm" regulated only by the Gun Control Act (GCA) that can be transferred by any "Free State" FFL.
