Any firearm's overall length may be reduced with a bullpup design without sacrificing the length of the barrel. This greatly improves the weapon's maneuverability, concealability, and compactness. The SDS Imports BLP M12AB shotgun is a 12 gauge semi-automatic bullpup shotgun. It features a barrel made of 4140 steel with a 3′′ chamber and is threaded to take chokes in the Benelli style. An adjustable cheek riser with a rubber buttpad to reduce felt recoil is located on the bullpup stock. The M12AB also has an ambidextrous magazine release, an AR-style safety selector switch, and a combination angled foregrip that makes it very simple to handle. The capacity is 5+1 rounds. A bullpup shotgun is for someone who prefers a shorter shotgun without making any other compromises.
