SPRINGFIELD ARMORY Hellion Bullpup 5.56 NATO / 223 Rem 20" 10rd Semi-Auto Rifle, CA Compliant. The California compliant Hellion is a 5.56mm bullpup rifle configured for residents of California. This variant features a Strike Industries pistol grip, fixed stock and SA Muzzle Brake for reduced recoil and enhanced precision. With an innovative bullpup configuration where the action is located behind the trigger, the Hellion maintains a 20-inch barrel for increased down range performance without sacrificing overall length. The Hellion sports ambidextrous controls that pair with a reversible case ejection system, allowing it to be easily fired from either shoulder. The result? A 5.56mm rifle that combines portability with performance.
SA MUZZLE BRAKE The precision-engineered SA Muzzle Brake is designed to reduce recoil by redirecting gas.
STRIKE INDUSTRIES PISTOL GRIP The Strike Industries pistol grip satisfies California's restrictions without compromising strength or function.
