The GFBP is a short and handy Shotgun in the classic bullpup configuration with the action and magazine behind the trigger. Bullpup shotguns accommodate a longer barrel without adding unnecessary length and allow you to hold the weapon closer to your body. The GFBP is just 29.5″ long making it ideal for the narrow corridors of home defense and tactical use. Features flip-up sights QD sling mount top and bottom Picatinny rails for optics and accessories. The Shotgun is compatible with MKA-1919 magazines and accepts 2 3/4″ and 3″ 12ga ammo. Includes 5rd magazine.
