The Springfield Armory Hellion, chambered in 5.56x45mm NATO, is engineered for operational efficiency and maneuverability. This bullpup semi-automatic rifle integrates a full-length 16-inch barrel into a compact chassis, offering optimized ballistics without compromising handling in confined spaces. KFF Defense assesses the Hellion as a robust, adaptable platform for demanding users requiring a high-performance, compact rifle.
Key Features
Bullpup Configuration
The Hellion’s bullpup design positions the action behind the trigger group, significantly reducing the rifle’s overall length while retaining a 16-inch barrel. This configuration maximizes ballistic performance and sight radius while providing a well-balanced platform that is agile in close quarters and stable for precision engagements.
Ambidextrous Controls
Designed for universal adaptability, the Hellion features a user-configurable ejection system, along with ambidextrous safety selector, magazine release, and charging handle. This ensures seamless operation for both left and right-handed shooters without requiring specialized tools for conversion.
Integrated Picatinny Rail System
A full-length MIL-STD-1913 Picatinny rail runs along the top of the receiver, facilitating direct attachment of primary optics, lights, and other mission-critical accessories. Additional M-LOK slots are integrated into the polymer handguard for further modular customization.
Adjustable Gas System
Equipped with a 2-position adjustable short-stroke gas piston system, the operator can optimize performance with various ammunition types or when utilizing a suppressor, mitigating excess recoil and ensuring reliable cycling under diverse conditions.
Precision 16-inch Barrel
The cold hammer-forged 16-inch barrel is chambered in 5.56x45mm NATO with a 1:7 twist rate, engineered to stabilize a wide range of projectile weights. It is threaded 1/2×28 and fitted with a proprietary flash hider to mitigate muzzle flash signature during operation.
Ergonomic Design
Features an adjustable polymer stock that provides multiple length-of-pull settings and an adjustable cheek riser, allowing for precise shooter interface customization. The Olive Drab Green (ODG) finish offers a low-visibility aesthetic and enhanced corrosion resistance.
High-Capacity Magazine Compatibility
The Hellion ships with a 30-round STANAG-compatible magazine, ensuring broad interoperability with existing AR-pattern magazine inventories.
