The Strike Industries T-Bone Charging Handle for .223/5.56 AR-15's feature a patented gas redirect system that allows you to configure the gas to exit only left, only right or evenly to both sides. The shaft of the charging handle is machined from 7000 series aluminum which excels in applications requiring lightweight and high strength. However, with comfort and control in mind, the T-Bone latchless handles are made from SI PolyFlex polymer.
