In their Instructional Overview Series, AirRattle goes over the VFC HK MP7 Gas Blowback SMG which is right now available at their online store... "The VFC H&K MP7 Navy is a true 1:1 scale airsoft variant of the real-steel Heckler & Koch MP7A2. Instead of the standard folding vertical grip found on most MP7A1 airsoft replicas, VFC has implemented the maritime-style railed handguard that features a full rail system. Externally, the dimensions of this airsoft gun perfectly match its real-steel counterpart in every detail from the stock to the iron sights. The body is made out of nylon-fiber polymer that is incredibly durable."
