From the manufacturer

A direct descendent of the HK416, the MR556 is a semi-automatic rifle developed by Heckler & Koch as a premium level commercial/civilian firearm. Like the HK416, the MR556 is a major product improvement of conventional AR-type carbines and rifles. Using the HK-proprietary gas piston system found on the HK416 and G36, the MR556 does not introduce propellant gases and carbon fouling back into the rifle's interior, making it the most reliable of any AR-type firearm. The MR556 uses many of the assemblies and accessories originally developed for the HK416 series arms including the HK free-floating four-quadrant rail system/handguard. This system allows all current accessories, Troy Micro mechanical sights, lights, and aimers used on M4/M16-type weapons to be fitted to the MR556. The HK rail system can be installed and removed without tools and returns to zero when reinstalled. Like the famous HK416, the MR556 uses a barrel produced by Heckler & Koch's famous cold hammer forging process. The highest quality steel is used in this unique manufacturing process producing a barrel that provides superior accuracy for more than 20,000 rounds with minimal degradation of accuracy and muzzle velocity.
