HK MR762 A4 LR-308 Complete Upper Receiver 7.62x51mm NATO 13" Barrel

This HK MR762 A4 kit includes a complete upper receiver/barrel assembly. This kit is only compatible with a MR762 lower . This closed system virtually eliminates the malfunctions that are common in direct-impingement gas systems, since hot carbon fouling and waste gasses are not propelled into the receiver area to operate the action. This is the same key feature critical to the success of the HK417 used by elite military and law enforcement customers. Upper will ship in HK Soft case. FeaturesCo
