Springfield Armory HL918556B Hellion Bullpup 5.56x45mm Rifle

For shooters seeking a radically innovative and exceptionally compact 5.56x45mm rifle without sacrificing ballistic performance, the Springfield Armory® Hellion™ bullpup stands as a groundbreaking solution. This isn’t just another modern sporting rifle; it’s a meticulously engineered firearm designed to redefine versatility and adaptability in diverse shooting environments. If you’re wondering how to achieve the maneuverability of a short-barreled rifle while maintaining the velocity and accuracy typically associated with a much longer barrel, the Hellion is your answer. It’s the ultimate choice for those who demand superior handling, reliability, and modularity in a single, formidable package.

Whether you’re engaging in competitive shooting, participating in tactical training, ensuring home defense, or simply enjoying a day at the range, the Springfield Armory Hellion offers a unique blend of features that cater to a wide array of demanding applications. Its innovative bullpup design solves the classic conundrum of balancing a rifle’s overall length (OAL) with its barrel length, providing an optimal platform for both close-quarters engagements and extended range precision.

Why Choose a Bullpup Rifle Like the Springfield Armory Hellion?

The core innovation of the Hellion lies in its “bullpup” configuration. But what exactly does that mean for you, the shooter? In a bullpup design, the action and magazine are located behind the trigger group, allowing for a significantly shorter overall rifle length while retaining a full-length barrel.

• Exceptional Compactness: Imagine a rifle with an 18-inch barrel that handles like a much shorter firearm. The Hellion’s design achieves an impressively short overall length (OAL) of 30.25 to 31.75 inches, making it incredibly agile and easy to maneuver in confined spaces such as vehicles, hallways, or dense brush. This compact footprint is a game-changer for tactical operators, home defenders, and even hunters navigating challenging terrain.
• Uncompromised Ballistics: Unlike traditional rifle designs where a shorter barrel means reduced muzzle velocity and projectile energy, the Hellion’s bullpup layout allows it to maintain an 18-inch barrel within its compact frame. This longer barrel length is crucial for maximizing the ballistic potential of the 5.56x45mm NATO cartridge, ensuring higher velocities, flatter trajectories, and greater terminal performance at extended ranges. You get the power of a full-size rifle in a package that handles like a carbine.
• Superior Balance: The rearward weight distribution of a bullpup often results in a rifle that feels more balanced and natural to hold, reducing perceived weight and improving off-hand shooting stability. This translates to reduced shooter fatigue during prolonged use and quicker target acquisition.

Designed for Every Shooter: Ambidextrous Controls and Adaptability

One of the standout features of the Springfield Armory Hellion is its unwavering commitment to user-friendliness, regardless of your dominant hand. This rifle is engineered from the ground up to be fully ambidextrous, ensuring seamless operation for both left- and right-handed shooters.

• Fully Ambidextrous Controls: Every critical control point on the Hellion – including the safety lever, magazine release, and bolt release – is designed for intuitive manipulation from either side of the rifle. This eliminates the need for left-handed shooters to adapt to right-handed layouts or for any shooter to compromise their natural handling.
• Reversible Case Ejection System: A common concern with bullpup rifles for left-handed shooters is spent brass ejecting uncomfortably close to the face. The Hellion addresses this with an innovative and easily reversible case ejection system. This allows the shooter to reconfigure the rifle to eject spent casings from either the left or right side, providing a truly customizable and comfortable shooting experience for everyone. This thoughtful design ensures maximum adaptability and prevents any performance compromises based on handedness.
• Quick Detach (QD) Sling Mount Points: For enhanced portability and readiness, the Hellion comes equipped with multiple Quick Detach (QD) sling mount points on both sides of the rifle. This allows you to attach your preferred sling system and configure it for optimal comfort and carrying, whether you’re transitioning between positions, securing the firearm, or carrying it over long distances. The ambidextrous placement of these points further supports the rifle’s versatile nature.

Precision-Engineered Barrel for Durability and Performance

The heart of any rifle’s performance lies in its barrel, and the Springfield Armory Hellion boasts a meticulously crafted 18-inch barrel designed for both accuracy and longevity.

• 18″ Chrome Moly Vanadium Steel Barrel: This robust barrel material is known for its strength, durability, and resistance to wear, making it an excellent choice for a hard-use rifle. The 1:7″ twist rate is ideal for stabilizing a wide range of 5.56x45mm projectile weights, from lighter, faster rounds to heavier, more precise options, ensuring consistent accuracy across the board.
• Black Melonite® Coating: The barrel features a Melonite® finish, a cutting-edge treatment that hardens the steel surface. This provides exceptional corrosion resistance, superior lubricity, and increased barrel life compared to traditional chrome lining. This means your Hellion will withstand harsh weather conditions, resist fouling, and maintain its precision for thousands of rounds, reducing maintenance demands and increasing reliability.
• 4-Prong Flash Hider: The muzzle of the Hellion is fitted with an effective 4-prong flash hider. This design significantly reduces muzzle flash, a critical feature for maintaining night vision, preventing distraction in low-light environments, and minimizing the shooter’s visible signature. It contributes to both shooter comfort and tactical effectiveness.

Optimized for Reliability: Adjustable Gas System

Reliability is paramount in any firearm, and the Springfield Armory Hellion ensures consistent performance across various ammunition types and operating conditions with its adjustable gas system.

• Two-Position Adjustable Gas Block: The Hellion features a user-friendly two-position adjustable gas block with clearly marked “S” (suppressed) and “N” (normal) modes.
  • “N” (Normal) Mode: This setting is optimized for standard ammunition and unsuppressed operation, ensuring reliable cycling and efficient gas management.
  • “S” (Suppressed) Mode: When running a suppressor, this mode reduces the amount of gas directed back into the system, mitigating over-gassing issues such as excessive recoil, increased fouling, and premature wear. This feature makes the Hellion an excellent host for suppressors, providing a smooth and comfortable shooting experience while preserving the rifle’s longevity.
• Adapting to Conditions: This adjustable gas system allows you to fine-tune the rifle’s operation to adapt to different ammunition loads, environmental conditions, or suppressor use, ensuring unwavering reliability and optimal performance every time you pull the trigger.

Modular Design for Enhanced Customization

Modern shooters demand the ability to customize their firearms to suit specific needs and preferences. The Springfield Armory Hellion excels in modularity, offering ample space for accessories and optics.

• Full-Length Picatinny Top Rail: The Hellion incorporates a robust, full-length Picatinny rail along the top of the receiver. This industry-standard rail provides ample real estate for mounting a wide variety of optics, from red dot sights and holographic weapon sights to magnified scopes and night vision devices, allowing for precise and secure attachment.
• Integrated Flip-Up Sights: Ready out of the box, the Hellion includes integrated flip-up front and rear sights. These durable polymer sights provide reliable backup iron sights that can be quickly deployed or folded flat when not in use, ensuring you always have aiming capabilities.
• Polymer M-LOK® Handguards: The rifle features polymer handguards equipped with the popular M-LOK® attachment system. M-LOK slots along the sides and bottom of the handguard allow for direct attachment of lights, lasers, foregrips, bipods, and other tactical accessories, enabling you to configure the rifle precisely to your mission or preference without adding unnecessary bulk.
• Black Bravo Mod 3 Grips: The ergonomic Black Bravo Mod 3 pistol grip provides a comfortable and secure hold, promoting natural point of aim and recoil control. Its textured surface ensures a firm grip even in adverse conditions.

Comprehensive Protection: Included Rifle Case

The value proposition of the Springfield Armory Hellion extends beyond the rifle itself. Each Hellion (UPC: 706397969448) comes with a high-quality, padded rifle case, ensuring your investment is protected from the moment it leaves the store.

• Padded Foam Shell: The rifle case features a durable padded foam shell that provides excellent shock absorption, safeguarding the rifle from impacts during transport. This protection is vital for maintaining the rifle’s zero and preserving its components.
• Adjustable Interior Velcro Straps: Inside the case, adjustable Velcro straps securely hold the rifle in place, preventing movement and minimizing wear on the firearm and any mounted accessories. This ensures that even delicate optics remain protected and properly aligned.
• Exterior Magazine Pouches: For added convenience, the case includes two exterior magazine pouches designed to hold standard pattern AR-15 magazines. This allows you to carry essential ammunition alongside your rifle, keeping everything organized and readily accessible.
