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. 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 its side-sliding unlocking action. The RACK is no doubt the new heavyweight champion among all other ambidextrous charging handles. Engineered to withstand the abuse of downrange use! Features : Fits AR15/M16 Platforms Anodized Finish, Olive Drab Green Ambidextrous Operation Made in the U.S.A.
