Product Features & Specifications
Springfield Armory HL918556B Hellion Bullpup 5.56x45mm Rifle
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.
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.
Rifle Case Included
A padded rifle case is included with each Hellion. The foam shell and adjustable interior Velcro straps ensure the rifle and any mounted optics are protected during transportation. The case also features two exterior magazine pouches for standard pattern AR-15 magazines.
