The Springfield Armory Hellion is a 5.56 NATO semi-automatic bullpup rifle finished in Flat Dark Earth (Springfield Armory part no. HL916556F), built to pack a 16-inch barrel into a footprint barely longer than two feet. Unlike a traditional semi-auto rifle, the Hellion’s bullpup layout places the action behind the trigger group, so shooters get full-length ballistic performance in a rifle that’s easier to maneuver in tight spaces like a vehicle, a blind, or a home hallway. Fully ambidextrous controls mean the rifle runs the same whether you shoot right- or left-handed. It ships with one 30-round magazine and flip-up front and rear sights, ready for a red dot or your favorite optic on top of the receiver.
