Springfield Armory Hellion 5.56 NATO 20in

The Springfield Armory Hellion is a bullpup-configured semi-automatic designed to deliver 5.56 NATO performance in a compact, maneuverable package suitable for range use and precision-oriented shooting. The Hellion's 20-inch barrel preserves downrange ballistics while the bullpup layout reduces overall length for easier handling.

The Hellion's design pairs a synthetic bullpup stock with integrated controls and modern ergonomics. The rifle incorporates M-LOK compatible handguards and an ambidextrous, non-reciprocating charging handle to support diverse shooter preferences. Integrated flip-up sights and a featureless grip wrap are included on the California-compliant configuration described in the product data.
