CW Flash Hider on CCW Barrel?

[Super64]

Is there a thread adaptor that will allow me to fit a cw flash hider onto a ccw barrel? I know you can get them the other way round, but I can’t seem to find it cw onto ccw. I accidentally bought a cw 4 prong flash hider which won’t fit onto any of my rifles so before I sell it on I’d like to know if it’s usable.
