The Springfield Armory Hellion bullpup rifle in 5.56 NATO with a black finish (brand part no. HL920556BLC) is a semi-automatic bullpup built around a full 20-inch barrel, placing the action behind the trigger for a compact overall footprint despite the long barrel. Springfield Armory cuts a 1-in-7-inch twist into the barrel and feeds the rifle from a 10-round magazine, a standard-capacity configuration. Low-profile flip-up front and rear sights ship standard for reliable target acquisition. Among bullpup semi-auto rifles, this Hellion configuration favors shooters in restrictive-capacity jurisdictions who still want the Hellion’s compact platform.
