Springfield Armory Hellion 5.56 NATO 18″ Bullpup 30rd

About this product

The Springfield Armory Hellion is a bullpup-configured semi-automatic rifle chambered for 5.56 NATO that combines a compact overall length with an 18-inch barrel for enhanced ballistic performance compared with shorter-barreled platforms. The action sits behind the trigger for a shorter footprint while retaining an 18″ barrel. Controls are fully ambidextrous, featuring reversible case ejection, an ambidextrous non-reciprocating charging handle, and a two-position adjustable gas block for suppressed and standard operation.
