The Panzer Arms BPA12 Bullpup Shotgun is a gas-operated, semi-automatic shotgun designed to look and function similar to popular bullpup rifles on the market. The BPA12 is designed to offer full size tactical shotgun performance in a smaller package. The bullpup design allows for a full length barrel, while still remaining short and compact, making the BPA12 ideal for home defense. The top of the receiver has an integral picatinny rail for mounting rear sights, optics, or accessories. The forend grip is removable to match user preference. The upper receiver is manufactured from an aluminum alloy, while the lower receiver, pistol grip, and stock are manufactured as one piece from impact resistant polymer.
