This is the Wider version of the Car Cannon Adapter
This is an adapter for the Streetwise Car Cannon. This plugs into the 5mm port on the rear of Streetwise's vehicle mode and creates a 5mm peg on the vehicle. By itself, the adapter can be used as a hand held weapon. It has 5mm ports to combine with other transformer weapons. This is compatible with similar molds like Combiner Wars Prowl (or similar molds like Streetwise, Smokescreen, Dead End, Break Neck, Lightsteed and more).
