The Polarstar equiped 416C is the subcompact version of the 416 and is the smallest of the HK assault family. The real firearm was designed for the British special forces and marketed to the US Special Ops units. Our HK 416C AEG is perfect for your indoor CQB style play. NOTE: You will need to get a tank and air rig to go with this gun. We recommend a tank with a SLP regulator and any one of the air rigs sold on our site. Polarstar FCU battery not included either.
