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 2-30rd magazines and a Single-Point Sling.
