I will be honest, I have only seen that happen on a few guns and said models were known for issues.
But on TMs, KWAs, KSCs, WAs, some WEs, some Army's and many others like HFC, KJ and the even lesser clone makes have lasted with the standard cast parts.
Maybe it depends on how they are run and treated too, but I have only seen issues in issue prone guns with the odd exception that you can't really blame on anything other than just lack of luck in getting a mediocre part.
