This issue has been going on for some time with the Remingtons. My understanding is that certain models manufactured during a certain period were more likely than others to have this problem. Also, this tended to happen more with people who did trigger work on their rifles making them more hair triggers than standard factory settings. For what it's worth I have a Remington 700 that has had none of these issues.
I don't know, some of the engineering stuff/cost cutting seems legit.Probably the exact same segment they have shown in the past. Whenever 60 Minutes needs to push anti-gun nonsense, they use this one to show that even hunting rifles are dangerous baby-killing monster machines!!!
