When I had my TM MP7, I used an Omega Nub with Maple Leaf bucking. However, I had to install a spacer between the hop arm and the nub in order to get any pressure on the bucking. I just cut out a small rectangle from an eraser and it worked perfectly. I imagine you could do the same with the SixG supernub, but I don't know what the results will be.
It was probably one of the most consistent and accurate guns I've ever used. Such a shame the magazines have a retarded design and the frame is pot metal/breaks with green gas usage...
