Springfield Armory Hellion 5.56 NATO

The Springfield Armory Hellion is a bullpup-configured semi-automatic rifle chambered in 5.56x45mm NATO (.223 REM) and intended for compact handling and versatile range use. Its bullpup layout shortens the overall length while retaining an 18-inch barrel to balance maneuverability with ballistic performance. The Gear Up package for this model includes an included red/green dot optic and a sling.

The Hellion pairs a polymer M-LOK handguard and an adjustable stock with a cheek riser for ergonomic fit and modular accessory mounting. Ambidextrous controls and a reversible ejection system support adaptability for a variety of shooters, while a two-position adjustable short-stroke piston gas system aims to provide consistent operation.
