They say bullpup designs are the future of the weapons industry, and exactly for that reason, we are here with the D-B12M Tank12, the next generation of the bullpup design. With this 12 gauge shotgun, we are offering you a more convenient and enjoyable experience. Tank12 has an ambidextrous magazine release button that is similar to the position of an AR15 mag release. The ambidextrous charging handle is closer to the center of the gun to ensure easy operation of the gun. Tank12 has the Defenceport pistol grip that can be swapped to adapt to shooters' needs. The Tank12 comes with high-profile front and rear sights for more comfortable aiming. We followed our principle of durability and added the barrel nut locking system and a bolt buffer piece for smoother cycling and increased lifetime of your shotgun. Just like all our magazine-fed shotguns, Tank12 is fully compatible with Defenceport’s signature 20 and 30-Round DRM-12 Drum Magazines.
