This upper receiver kit is built on the Heckler and Koch MR762A4 platform and chambered in 7.62mm NATO, with a 13-inch barrel. HK's MR762 is the semi-automatic civilian version of a design known for its short-stroke gas piston and military-grade durability. An upper kit lets owners of compatible lowers change configuration or build out their rifle with proven German-engineered hardware. Verify compatibility with your lower before purchasing.
