The FishLab Mack Attack Replacement Bodies are custom designed to be rigged on the jig head that comes with the Mack Attack Soft Swimbait. Replacement bodies are a must when using the swimbait around toothy predators that can tear the bait, and also give you the opportunity to experiment with multiple colors without having to purchase another full swimbait. These bodies feature vivid detailing that is strikingly accurate to a live Atlantic Mackerel, including realistic coloration and proper fin placement for an anatomically accurate profile.
