Springfield Armory Hellion Bullpup | 5.56 | 16in | HL916556B

The Springfield Armory Hellion is a compact bullpup rifle built around the 5.56x45mm NATO cartridge. Its layout places the action behind the trigger to preserve a full-length 16-inch barrel while keeping overall length minimal. The Hellion includes ambidextrous controls, a reversible ejection system, integrated flip-up sights, and a two-position adjustable short-stroke piston gas system. For a mounted optic under $1,000 that complements this platform, consider a Vortex Strike Eagle 1-6×24 for fast close-range work and usable magnification at intermediate distances.

The Hellion offers a very compact footprint without sacrificing barrel length or common AR-15 ergonomics. Its bullpup layout and adjustable features make it suitable for range work and compact field carry where length and maneuverability matter. Robust ambidextrous controls and the reversible ejection system increase flexibility for different shooters and setups, while the piston gas system helps tune performance for suppressed or unsuppressed use. If you want a short, capable 5.56 platform that keeps a full 16-inch barrel, the Hellion provides that in a modern, user-configurable package.
