Like the HK416, the MR556A1 is a major product improvement over conventional AR-type carbines and rifles. The Heckler & Koch MR556A1 uses the HK proprietary gas piston operating system, employing a piston and a solid operating “pusher” rod in place of the gas tube normally found in AR15/M16/M4-style firearms. This method of operation virtually eliminates malfunctions that are common to direct impingement gas systems since hot carbon fouling and waste gases do not enter the receiver area. This is the same key feature critical to the success of the HK416 rifles used by leading military and law enforcement customers. Barrel has a 1 in 7 inch twist and stock is a Six postion adjustable.
