Redefining perceptions of semi-automatic 5.56 performance, the new Hellion from Springfield Armory represents a radically unique and innovative approach to firearms design. 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, allowing it to be easily fired from either shoulder. The result? A 5.56 that combines portability with performance.
