HK MR556A1 16.5″ -5.56NATO

The HK MR556A1 16.5″ -5.56NATO is a civilian descendant of the HK 416 rifle. This firearm is a rare firearm with a 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. Heckler & Koch MR556A1 16.5″ -5.56NATO uses a German-made, cold hammer-forged barrel that is battlefield tested for law enforcement/military purposes. It also comes with HK branded adjustable stock and grip, and has a free-float MLOK handguard around the barrel, and shipped in a tactical rifle range bag.
