Springfield Armory's Hellion answers the call for superior ballistic performance in a short, adaptable platform. Featuring a bullpup configuration where the action is located behind the trigger. The Hellion bullpup features a two-position adjustable gas block with suppressed and normal modes; ambidextrous controls that work in concert with a reversible case ejection system; Picatinny top rail; flip-up iron sights. These spring-loaded sights quickly pop into position, locking solidly until released. It accepts standard AR-15 pattern grips. The polymer handguard features 9 M-Lok slots for mounting accessories. Includes soft case and two exterior magazine pouches for standard pattern AR-15 magazines.
