The funny thing about NiB is it shows off tool marks. We ran into this with our first batch of NiB BCGs and we also stock the .308 match NiB unit that you're posting about. Ours also have some toolmarks which we've basically come to expect with NiB BCGs. An additional step in the process prior to plating which isn't done with phosphated/parkerized BCGs but should be done with NiB is to polish the surface to be plated. It's purely an aesthetic issue, not a functional one provided that the bearing surfaces are smooth.
