This shotgun has some ridiculous speed due to a fairly innovative operating mechanism. All ammo used was full power buckshot and slugs. Today we take a dive on the Genesis Arms 12, a semi automatic magazine fed shotgun that actually works. We've previously reviewed a version of this gun but due to the change in operating system we felt it deserved a new video. The Gen 12 is made right here in Idaho and we're a fan. Hope you all enjoy the video.
