Springfield Armory Hellion 5.56 Bullpup 18" Rifle

Springfield Armory Hellion: Redefining the Bullpup

The Springfield Armory Hellion represents a bold departure from conventional rifle design. By placing the action behind the trigger in a true bullpup configuration, this 5.56 rifle achieves something remarkable: genuine compactness without sacrificing ballistic performance.

Design and Handling

With an overall length of just 30.25 to 31.75 inches, the Hellion excels in confined spaces—vehicles, tight quarters, or situations demanding rapid deployment. Yet its 18-inch barrel maintains the velocity and energy needed for effective 5.56 performance at practical distances.

Operational Features

The Hellion is built for shooters who demand adaptability:

• Ambidextrous Controls: Safety switch and charging handle work equally well for left and right-handed shooters
• Reversible Case Ejection: Eject brass to either side, accommodating your shooting position or preference
• Two-Position Gas Block: Switch between suppressed and normal operation without tools
• Integrated Flip-Up Sights: Spring-loaded front and rear sights with elevation and windage adjustment lock solidly in place

Accessories and Customization

The polymer M-Lok handguard provides nine mounting slots for lights, lasers, or other tactical accessories. The rifle accepts standard AR-15 pattern grips, giving you familiar ergonomics and endless customization options.
