When you need the absolute very best rifle that will work flawlessly no matter what conditions you're in, then you want the H&K MR556A1 Semi Auto Piston Rifle. This rifle is a direct descendent of the HK416, and has been developed by Heckler and 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 "pusher" rod in place of the gas tube normally found in AR15/M16/M4-style firearms. This gives it exceptional reliability and increase life.
