Designed for DPMS pattern 308 platforms. **Not compatiable with Armamlite® AR-10 or SIG716** 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. The RACK™ is no doubt the new heavyweight champion among all other ambidextrous charging handles. Engineered to withstand the abuse of downrange use!  Package Contents (1) RACK™ Charging Handle   Features Weight: 1.48ozMaterial: 7075 Billet AluminumFinish: Black Hard Coat Anodize Proudly Made In The USA!
