Hellion™ 5.56 18″ Rifle, Low Capacity – Firstline UPC: 706397977856

The Springfield Armory® Hellion™ 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 18” features a short overall length for compact handling along with enhanced ballistic performance due to its longer barrel. Ambidextrous controls work in concert with a reversible case ejection system for maximum adaptability. The result is a 5.56 that combines portability with potent performance. Shipping with a 10-round magazine, the low capacity variant allows customers in states with magazine capacity restrictions to own this legendary rifle.
  • QD Points

    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.

  • 18" Barrel

    The 18" barrel features a four-prong flash hider and durable Melonite® coating for corrosion resistance.

  • Adjustable Gas System

    The Hellion 5.56mm bullpup features a two-position adjustable gas block with “S” suppressed and “N” normal modes to adapt to conditions and ammo availability.
