Gunner Airsoft has in stock a Chinese made M72 light anti-tank weapon (LAW)  that can take in 40mm gas grenades. Made of plastic and some metal parts which we assume are the sighs and operating mechanisms, it costs US$255, which is kind of expensive for a single purpose launcher. Well, one thing for sure, it's not a disposable launcher unlike the real one it was based on. Nice to have this as props in the skirmish field.
