I checked them too. & came away with exactly what you found. I checked a couple other sites & found nothing. Guess I'll just go with the NECG .630 size. Was thinking maybe there is a coating available that could be close to stainless in color. Problem, it may look shade tree hokey. Just leaving them white seems to be the best way. I did notice Brownell's charges more for the NECG site's than buying them direct from NECG. Strange. Well thanks Jim your moral support alone has been great.
