Springfield Armory Hellion | 5.56 NATO | 20″ | 30+1

The Springfield Armory Hellion is a compact bullpup semi-automatic rifle built around a 20″ CMV Melonite barrel and a short overall length. It features fully ambidextrous controls, a reversible ejection system, and a two-position adjustable gas block to support suppressed or unsuppressed operation. The Hellion ships with integrated flip-up front and rear sights, an M-LOK polymer handguard, and accepts standard AR-15 pattern magazines. For optics, a low-power variable such as the Vortex Strike Eagle 1-6×24 pairs well with this platform while remaining under $1,000.
