PMT (Percision Molded Technology) allows Combat engineers to design barrel wall thickness to maximize barrel trampoline effect & bat performance. * BFT (Blended Fiber Technology) is used to create more trampoline effect without sacrificing durability. * GT (Gear Technology) has a special taper in the barrel, which provides a softer feel and greater performance. * ACT (Anisotropic Composite Technology) varies stiffness along the handle reducing sting and across the barrel for softer feel and improved bat performance. * Approved for play in LLB, DIXIE, PONY, AABC, BABE RUTH, and USSSA.
