Springfield Armory Hellion 5.56 NATO | 18in | HL918556BLC-GU25

The Springfield Armory Hellion is a bullpup-configured semi-automatic rifle chambered in 5.56x45mm NATO featuring an 18″ CMV Melonite-treated barrel and ambidextrous controls. Its rearward action produces a compact overall length while retaining ballistic performance from the longer barrel. This Gear Up package includes a Crimson Trace CT-103 red/green dot optic and a single-point sling. Well-suited optics under $1,000 for this platform include compact reflex sights such as the Vortex StrikeFire II.

Common applications for the Hellion are range training and precision-oriented small-game or varmint work where a compact handling profile with a full-length barrel is desirable.
