Springfield Armory Hellion 5.56 NATO Bullpup Rifle - 16" Barrel

The Springfield Armory Hellion 5.56 NATO rifle delivers bullpup configuration advantages in a proven semi-automatic platform. This rifle maintains full-length barrel performance while reducing overall weapon length by 7-9 inches compared to traditional AR-15 configurations.

What Makes This Different

The Hellion's bullpup design places the action behind the trigger group, achieving a 28.25-inch overall length with a 16-inch barrel. This configuration provides superior maneuverability in confined spaces while maintaining ballistic performance equivalent to full-size rifles. The ambidextrous ejection system adapts to left or right-handed shooters without modification, addressing a common limitation of bullpup platforms.

Key Features

• 16-inch chrome-lined barrel with 1:7 twist rate for optimal 5.56 NATO performance
• Ambidextrous ejection system converts without tools for left-handed operation
• Picatinny rail system with 15 inches of top rail space for optics and accessories
• Two-stage trigger system with 8.5-pound pull weight and crisp break
• NATO STANAG magazine compatibility accepts standard AR-15 magazines
• Integrated backup iron sights with adjustable rear aperture
• Quick-detach sling swivel mounts on both sides of the receiver

Field testing demonstrates consistent 2-3 MOA accuracy with quality ammunition, suitable for patrol rifle applications and competitive shooting. The gas system cycles reliably with ammunition ranging from 55-grain M193 to 77-grain match loads. Weather sealing protects internal components during adverse conditions, while the polymer stock construction resists impact damage.
