Hellion™ Rifles

Answering the call for superior ballistic performance in a short, adaptable platform Springfield Armory is proud to announce the Hellion. 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 5.56mm that combines portability with performance.


Unlike a traditional long gun, the bullpup system moves the action and the magazine back behind the trigger into the normally unused buttstock area. By doing this, it reduces the overall length drastically, while still allowing you to have a barrel long enough to retain effective downrange performance.

Based on the internationally proven VHS-2 bullpup, which has been employed by the Croatian armed forces in demanding environments ranging from Iraq to Africa and beyond, the Springfield Armory Hellion offers American shooters a semi-automatic 5.56mm version of this highly capable firearm.

  • Integrated Flip-Up Sights

    Integrated into the Picatinny top rail of the Hellion is a set of sturdy and capable flip-up iron sights. These spring-loaded sights quickly pop into position, locking solidly until released.

  • Picatinny Top Rail

    An uninterrupted strip of Picatinny rail runs along the top of the Hellion, ensuring you can mount the optics of your choice to wring out the most performance from the 5.56mm bullpup.


    The Hellion accepts standard AR-15 pattern grips like the included Bravo Company USA® BCMGUNFIGHTER™ Mod 3.

  • Adjustable Stock

    The Springfield Armory Hellion 5.56mm bullpup ensures maximum adaptability to a wide range of shooters through its spring-loaded, five-position adjustable buttstock.

  • M-Lok® Compatible

    The polymer handguard of the Hellion features nine M-Lok slots for mounting accessories, three each at the 3, 6 and 9 o’clock positions.

  • Included PMag

    The Springfield Armory Hellion 5.56mm bullpup is designed to feed from AR-pattern magazines and comes with a 30-round Magpul® PMAG.


The Hellion bullpup houses a hammer forged 16″ barrel chambered in 5.56, giving the rifle a high performance precision barrel for maximum accuracy. With a 1:7″ rate of twist and a rugged Melonite® coating, the Hellion delivers impressive ballistics and amazing downrange performance for its compact size.


The Hellion features a reversible ejection system for fired cases that requires no additional parts or tools. Complementing this system is a set of fully ambidextrous controls, including the safety, charging handle, magazine, and bolt releases. The result is an ultra-compact 5.56mm that can be easily fired from either shoulder.



To ensure the maximum in flexibility and performance, the Springfield Armory Hellion 5.56mm bullpup features a two-position adjustable gas block with “S” suppressed and “N” normal modes. The result is a firearm that can be easily and quickly adjusted to fit conditions and ammo availability.
