Overview
H&K MR762 A4 13" Upper Receiver Kit
Upgrade your rifle with the genuine H&K MR762 A4 13" Upper Receiver Kit, a factory OEM upper assembly engineered by Heckler & Koch for exceptional reliability, accuracy, and long-term durability.
Designed exclusively for compatibility with HK MR762 lower receivers, this complete upper receiver assembly delivers the proven performance of HK's legendary short-stroke gas piston operating system.
The HK piston-driven system keeps hot gases, carbon fouling, and debris out of the receiver. This results in a cleaner-running rifle with reduced maintenance requirements and enhanced reliability during extended shooting sessions. The same battle-proven operating system is derived from the HK417, a platform trusted by military and law enforcement professionals around the world.
Upper will ship in HK Soft case.
