The Hellion from Springfield Armory represents a radically unique and innovative approach to firearms design, helping to redefine perceptions of semi-automatic 5.56mm performance. Featuring a “bullpup” configuration where the action is located behind the trigger, the Hellion features an overall length of just 28.25-inches while still possessing a 16” barrel. The Hellion sports ambidextrous controls that work in concert with a reversible case ejection system. The result is a 5.56 that combines portability with potent performance. The Hellion comes with QD mount points on both sides of the 5.56mm bullpup, ensuring you can use the sling of your choice, arranged for use from either side. The rifle also features a two-position adjustable gas block with “S” suppressed and “N” normal modes to adapt to conditions and ammo availability.
