The Springfield Armory Hellion 5.56 NATO 16" Low Capacity redefines semi-automatic performance by adapting the battle-proven Croatian VHS-2 military architecture into a premier bullpup design. By positioning the action behind the trigger group, this platform maintains an ultra-compact overall length of under 30 inches while retaining a full 16-inch hammer-forged barrel for optimal ballistic velocity. It offers a fully ambidextrous interface complete with a non-reciprocating charging handle and a tool-less reversible case ejection system that lets left- and right-handed marksmen operate seamlessly from either shoulder. Cycling reliability is managed by an adjustable two-position short-stroke gas piston system tuned for both suppressed and normal operations, running in unison with premium low-profile integrated flip-up sights. Complete with a polymer M-LOK handguard, a BCMGUNFIGHTER Mod 3 grip, and a unique 5-position adjustable buttstock with a built-in cheek riser, this compliant, duty-ready rifle ships with a 10-round Magpul PMAG and a custom padded transport case.
