Red Jacket Firearms redefines armored cars when they conceal fully automatic M-16s and Claymore mines in an armored Porsche for a client that needs protection as well as the ability to fight back. Meanwhile, Steph goes rogue and builds a custom AR behind Will's back. And Jesse James returns to Red Jacket with his engraved BAR parts. The team assembles his gun and together they take it to the range where Jesse fires the custom-built weapon.
