The Super X4 is lighter, faster cycling, smoother swinging and more ergonomic than ever before. The self-adjusting active valve system cycles a wide variety of loads while reducing "felt recoil", while an active valve system adjusts gas pressures using Quadra-Vent technology. Quadra-Vent Ports vent excess gases for cleaner operation. Its stock features improved ergonomics, a smaller pistol grip and textured gripping surfaces give your hands a sure, non-slip grip. It also utilizes LOP spacers and a Inflex technology recoil pad. The SX4 barrel features back-bored technology and Invector-Plus choke tubes.
