Airsoft2Go got the Tokyo Marui Type 89-F GBB Rifle with the Zet System found in the MWS series... "The Type 89 rifle with a folding stock, adopted by the Japanese Army, specifically the Ground Self-Defense Force 1st Airborne Brigade. The Airsoft is very stable thanks to an integrated aluminum alloy outer barrel and a die-cast upper / lower receiver. Just like the original, the Airsoft is made of metal and polymer parts, so the surface and weight is very close to the original."
