New for 2011, these A5s feature the HE E-Grip which allows users to fire up to 20 balls-per-second! There are five different special firing modes to choose from including Semi-auto, Auto-response, Full-auto, 3-shot bursts and Turbo. Its new external selector switch enables you to change from safe, to fire, to special firing modes on the fly. It has an improved, faster cyclone feed system and new barrel that is more accurate and quieter than the original. Some other added features are a larger, removable frontgrip, front sling mount, a lighter magnesium body and a lower-profile loader design.
