Decent shape but used air america Armageddon Regulator. Multiples available so actual item you receive will be different from photo but style and condition of Armageddon will be the same.
Has first stage regulator on the tank and second stage block regulator for mounting under grip frame. Threads on tank mount reg are proprietary, my favorite hpa system. Untested. Has gunk inside of gills of Aluminum block, doesn't have too many scratches, set screws marks on top of rail. Has wrench marks on first stage reg that screws into tank but looks decent otherwise.Will need a rebuild.
