MR762 A4 13” .308 Assaulter Upper Receiver Kit
The latest update from HK-USA for the commercial version of the legendary HK417, the MR762 A4, highlights an improved example of "No Compromise" HK performance. It is now available as a 13-inch Assaulter standalone upper receiver group.
The MR762 A4 Assaulter upper features a 13 inch cold hammer forged barrel chambered in .308 winchester / 762 NATO. The MR762 A4 upper also comes equipped with an adjustable gas block allowing the user to adjust the gas for suppressed & unsuppressed use.
The MR762 A4 uppers utilized a closed piston operating system that eliminates malfunctions common on direct impingement systems as it prevents carbon fouling and waste gasses into the receiver / action area. This same system is responsible for the legendary reliability that the HK417 platform is known for.
