This 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. Kit will start shipping late Q4 2025
