Battle Arms BAD-RACK-308: The Rack Ambidextrous Charging Handle is the toughest available for the AR-15, AR-10 and 9mm AR PCC platforms. The Rack charging handle is simplicity at its best with only three major components. Unlike other charging handles, the Rack makes no contact with the sides of the receiver preventing wear on the receiver and charging handle. Not only is it fast, buttery smooth, it also minimizes wear to the upper receiver with it\'s side-sliding unlocking action.
