Springfield Armory Hellion HL916556B Bullpup 5.56

Springfield Armory Hellion: Redefining Bullpup Performance

The Hellion represents a bold departure from conventional rifle design, placing the action behind the trigger in a true bullpup configuration. This arrangement delivers something rarely seen in modern 5.56 rifles: genuine portability without sacrificing ballistic capability.

Compact Without Compromise

With an overall length of just 28.25 inches and a full 16-inch barrel, the Hellion achieves what many thought impossible. You get the velocity and accuracy potential of a mid-length rifle in a package that handles like a carbine. This makes it equally at home in tight quarters or on open ground.

Engineered for Flexibility

Ambidextrous Operation — The Hellion's fully ambidextrous controls and reversible case ejection system allow either-shoulder firing without modification. Whether you're left or right-handed, this rifle adapts to you.

Adjustable Gas System — A two-position short-stroke piston system lets you select between suppressed (S) and normal (N) operation, ensuring reliable function across different ammunition types and configurations.

Five-Position Stock — The adjustable buttstock with integrated cheek riser accommodates various shooting positions and body types, while the spring-loaded design ensures positive engagement.
