CentralCNhunter,
Looks are secondary, function first! If the part works, that is all that matters, paint/blueing/ceracoat/ECT., is all nothing but coverings for pretties.
No animal is going to give 3 craps about whether your bolt catch looked good, but it will care more about your rifles correct function. And some POS is much more likely to care about failures, if that happens to be the tool 8n your hand when needed.
