I went looking for them and found this offering on Gunbroker by Vega Ballistics (for $4,500)
The Bulgarian RPG-7 rocket launcher started out as a demiled unit, and we painstakingly reactivated the fire control and have restored the launcher to like-new condition. External finish is not painted, but is a beautiful and very durable glossy powder-coated finish. The launcher is only capable of firing the PG-7 subcaliber unit, and cannot fire live rockets. The unit was evaluated by the Firearms Technology Branch of the BATF, and it is not classified as a destructive device, but rather a trigger mechanism for the subcaliber firearm.
