The GFBP is a short and handy Shotgun in the classic bullpup configuration (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. At only 3 inches longer than the Mossberg 590 Shockwave, The 29.5-inch GFBP is ideal for the narrow corridors of home defense and tactical use.
 
The GFBP bullpup shotgun is compatible with MKA-1919 magazines and accepts 2 3/4 and 3-inch 12ga ammo. The GFBP features adjustable flip-up sights, as well as a bottom Picatinny rail for mounting accessories. Red dots and reflex sights can also be installed on the GFBP for faster target acquisition.
