Springfield Armory Hellion Bullpup 5.56 NATO 16-inch FDE 30+1

The Springfield Armory Hellion is a compact bullpup semi-automatic rifle chambered in 5.56x45mm NATO with a 16-inch barrel and a 30+1 capacity. Its bullpup configuration shortens overall length while retaining a full-length barrel for ballistic performance in a more maneuverable package. The system uses a two-position adjustable short-stroke piston gas block and includes ambidextrous controls with a reversible case ejection option. The rifle is finished in Flat Dark Earth with polymer furniture and an M-Lok handguard.
