I'm going to answer my own question because I found the answer out - the QD cups cannot be removed. I have the bag rider fastener/screw pointed out as well above, but I (somebody can correct me if I'm wrong) believe that
can be removed, so no issue there.
I suppose the only option then is to somehow cover them, or just cerakote over them, but it does appear that there are several black parts that are basically just permanently buried/affixed to the chassis with no way to remove them.
Does anyone know if the buttstock folding button can be removed? That could be another one that would be tricky if not.
@Patch98 Whomever did the cerakote job on your MRAD, were they able to remove the folding buttstock button in the process? Or did they just cover that with something and cerakote around
