Product Features & Specifications

Springfield Armory HL920556B 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 20” features a short overall length for compact handling, as well as a bayonet lug. The Hellion sports ambidextrous controls that work in concert with a reversible case ejection system. 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.

20" Barrel 

Outfitted with a four-prong flash hider, the 20" barrel is ribbed for enhanced cooling and features a Melonite® coating for corrosion resistance. An integrated bayonet lug is true to the original design.

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.
