It seems like you’re obliquely arguing for something, since you say “it’s hard to keep control of who buys/sells them” and offer this as justification, but justification for what, exactly? I don’t think it’s reasonable to look at service pattern rifles in isolation to try to sort out whether they are a problem. They don’t seem to be a major contributor to gun deaths, overall — rifles of all descriptions contribute ~5% of gun deaths every year in the US. Their potential danger may seem great but the data does not bear that out.
