M6x20 is what I posted was the size of the stocks. Which I also did not re-use bec the CSF is far heavier than the stock to use that.
Someone posted this (below)…. but #12 is a smaller DIA compared to the M6. But longer.
Got #12x1-1/4" Torx screws and large washers along with some cushion washers from McMasterCarr.
