The GForce Arms GFBP in 12 gauge and black finish (brand part no. GFBP1220) is a gas-operated, magazine-fed bullpup shotgun built around an 18.5-inch barrel, placing the action and magazine behind the trigger to keep the overall package short and easy to maneuver. GForce Arms builds the GFBP with a polymer upper and lower, compatible with MKA-1919 magazines and running both 2-3/4-inch and 3-inch 12 gauge shells. Among semi-auto shotguns, the GFBP favors shooters who want a short, home-defense-ready bullpup only a few inches longer than a Mossberg 590 Shockwave.
