We have completed our prototype RPG 7 airsoft grenade launcher and are just waiting for eVike/UPS to bring us more green gas to try it out! These units should be available within a month to a month and a half and have an expected street price point around 400 dollars US.
Our current prototype isn't as pretty as we would like, having been modified a couple times and beaten severely in stress testing, so no pics for the time being. But hey, it's an RPG 7... they all look pretty much the same. And for those who may not know, an airsoft grenade launcher is actually more like a very large bore shotgun. The grenade shell fires a cloud of airsoft bbs instead of a single projectile (unless it is loaded with a foam ball instead of bbs, which can be done).
