Big_Jim The repressor upgrade (the whole reason I purchased this set) is way too big to fit on any rhinos I have. I have no idea if it will fit properly on any epic scale rhino - I don't have official GW Mark IIs which I suppose is what they're designed for. I'm having to green stuff the back overhang significantly for use on the Otter-ware version. The blade looks great, however.
The other pieces are also over-sized for my rhinos, But they were gravy in my world - the Repressor pieces were what I really wanted.
