Springfield Hellion Bullpup Rifle 5.56 .223 -- HL916556B

Per Springfield: 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 features an overall length of just 28.25-inches while still possessing a 16" barrel.

To ensure the maximum in flexibility and performance, the Hellion bullpup features a two-position adjustable gas block with S suppressed and N normal modes. It sports ambidextrous controls that work in concert with a reversible case ejection system, allowing it to be easily fired from either shoulder.

Integrated into the Picatinny top rail 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.
