The Hellion bullpup features a two-position adjustable gas block with S suppressed and N normal modes; ambidextrous controls that work in concert with a reversible case ejection system; integrated into the Picatinny top rail of the Hellion is a set of sturdy and capable flip-up iron sights, these spring-loaded sights quickly pop into position, locking solidly until released. It accepts standard AR-15 pattern grips like the included Bravo Company USA BCMGUNFIGHTER Mod 3. The polymer handguard features nine M-LOK slots for mounting accessories, three each at the 3, 6 and 9 o'clock positions. The Springfield Armory Hellion bullpup ensures maximum adaptability to a wide range of shooters through its spring-loaded, five-position adjustable buttstock. Gear up package includes a Vortex Crossfire Optic, two 30rd magazines and a Single-Point Sling.
