I've got a Night Lords Contemptor that needs two butcher cannons, but the big ones from Forgeworld just look too large (which makes sense, given the size of the Decimator they are intended for).
What are you guys using for Butcher Cannons? I don't just want to use standard Kheres Assault Cannons, but a cool conversion might be distinct enough for me to use them.
Post some pictures or solutions! Thanks a lot Dakka!
