The RACK Ambidextrous Charging Handle was developed by BATTLEARMS to be the finest charging handle ever produced! It is the toughest available for the AR-15, AR-10 and 9mm AR PCC platforms. 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. The RACK is Engineered to withstand the abuse of downrange use!
