Springfield Armory Hellion 5.56 NATO 16 Inch Bullpup Rifle

Springfield Armory’s Hellion brings superior ballistic performance to a compact, adaptable platform built around bullpup mechanics. The action is positioned behind the trigger, enabling the short overall profile without sacrificing 5.56 NATO capability. A two-position adjustable gas block offers both suppressed and normal operating modes. Ambidextrous controls pair with a reversible case ejection system to accommodate shooters of any preference. The rifle ships with a Picatinny top rail and flip-up iron sights—spring-loaded designs that snap into position and hold securely until manually released. Standard AR-15 pattern grips are compatible. The polymer handguard incorporates 9 M-Lok slots for accessory mounting. Your purchase includes a soft case and two exterior magazine pouches sized for standard AR-15 magazines.
