Warsheep Tactical shares what he thinks about the VFC HK416A5 GBB which we believe is the Gen 3 version. This airsoft replica is a near-perfect copy of the real Heckler & Koch HK416 assault rifle, built to the same scale and weight with a metal and aluminum body, a sliding stock, and rails for customization. While the frame is metal like the real gun, the stock and grip are made of durable nylon fiber, and this latest version features an improved magazine system, ambidextrous controls, and an easier-to-adjust hop-up.
