About this product

The Springfield Armory Hellion is a compact bullpup rifle platform chambered for 5.56x45mm NATO with a 16″ barrel and an Olive Drab Green finish. Its bullpup layout locates the action behind the trigger to deliver a full-length barrel in a shorter overall package. The design includes ambidextrous controls, a two-position adjustable short-stroke piston gas system, and integrated flip-up iron sights for a practical, compact field rifle. The Hellion is intended for shooters who want a short, transportable platform while retaining a 16″ barrel and modern accessory compatibility.
