HK MR556A1 5.56mm NATO 16.5in Black Semi Automatic Modern Sporting Rifle – A direct descendent of the HK416, the MR556A1 is a semi-automatic rifle developed by Heckler Koch as a premium level commercial/civilian firearm with match rifle capability. Like the HK416, the MR556A1 is a major product improvement over conventional AR-type carbines and rifles. The MR556A1 uses the HK proprietary gas piston operating system, employing a piston and a solid operating “pusherâ€ rod in place of the gas tube normally found in AR15/M16/M4-style firearms.

Free Floating Rail System (FFRS) handguard has four MIL-STD-1913 “Picatinny” rails
The HK rail system can be installed and removed with simple tools and returns to zero when reinstalled
Picantinny rail machined into the top of its upper receiver for mounting optics and mechanical sights
The MR556A1 upper receiver/barrel assembly, are fully interchangeable with other high quality AR-style firearms
MR556A1 upper receiver kits can be used to retrofit competing legacy AR systems
