So you might ask, Why Fatal Shot? The MOJO Line of FATAL SHOT CHOKE Tubes is a result of a partnership between MOJO Outdoors and Rob Roberts Custom Gunworks. Roberts has spent a lifetime making shotguns pattern to their highest potential. He was one of the first to use state of the art computerized pattern analysis machines to evaluate how shotguns shoot. This allowed Rob to quickly and easily test many theories as to what made the best choke, until he developed the true Custom Choke tube that is the standard for Performance Shotguns. Today Rob provides performance upgrades for major gun companies such as Benelli USA. And now, Fatal Shot is the result of Roberts many years of experience in getting the optimum performance out of shotguns. Before Fatal Shot, hunters and shooters would have had to purchase an expensive Performance Upgrade to get a choke of this quality. Together with our WATERFOWL (Short, Medium, & Long Range), PREDATOR and TURKEY chokes, these 5 Chokes cover the entire shotgun hunting spectrum and other shooting sports!
