Assembled in the US using both German and US made components, using many similar components to the HK416 means this is the closest the initiated can get to owning the real thing. Like the HK416, the MR556A1 uses a proprietary HK Short Stroke gas piston system instead of the direct gas impingement system found on lesser AR-15 style rifles. This closed piston system does not allow the exhaust gasses to enter the receiver meaning the HK runs cooler, cleaner and more reliably.
