The HK 416 is the improved version of the well-known M4 / M16 models. The S-AEG in the Close Quarters Battle version is very compact and therefore easy to carry even in tight environments. The full-metal version with 3.2 kilos comes close to the original. The Generation V2 has an improved Metal Gearbox with built-in Mosfet. Rails allow attachment of a targeting device and other accessories.
