HK UPPER RECEIVER KIT MR762 A4 – 16″
The MR762 A4 upper kit contains a complete upper receiver and barrel assembly. The closed system design significantly reduces malfunctions typically associated with direct-impingement gas systems, as hot carbon fouling and waste gases are not introduced into the receiver area to operate the action. This feature is essential to the operational reliability and the success of the HK417. The kit is compatible exclusively with an MR762 lower receiver. The upper kit is shipped in an HK soft case.
