Springfield Armory Hellion 5.56 NATO 18″ Bullpup Rifle

Springfield Armory’s Hellion delivers superior ballistic performance in a compact, adaptable bullpup platform. The action is positioned behind the trigger, allowing for a shorter overall footprint while maintaining full 5.56 NATO capability from an 18-inch barrel. The rifle features a two-position adjustable gas block with suppressed and normal modes, letting you tune performance to your setup. Ambidextrous controls work seamlessly with a reversible case ejection system, making the Hellion equally suited to left and right-handed shooters. A Picatinny top rail provides mounting flexibility, while flip-up iron sights lock solidly in position and spring back down when not needed. The Hellion accepts standard AR-15 pattern grips and includes a polymer handguard with 9 M-Lok slots for accessory mounting. Each rifle ships with a soft case and two exterior magazine pouches compatible with standard AR-15 magazines.
