Im sorry i cant post a direct link to the other forum but its called Dougs and the board is green. If you cant find it just shoot me a PM for the link. He has another nice custom Knight with a Douglas barrel and a custom LRMP system too

I am not sure why the pics did not show up for GM54-120 but I think this is what he was trying to show.
