NALBANDIAN, Circuit Judge. Sometimes timing is everything. After this appeal, Gregory Raymore would almost certainly agree. A jury convicted him as a felon in possession of a firearm before the Supreme Court decided a case that heightened that offense’s mens rea requirement. Understandably, he failed to challenge his indictment and the court’s jury instructions on that basis until this appeal. Given that, we review those challenges only for plain error and they fail under that standard. The other arguments he raises against his conviction and his sentence also fail. So we AFFIRM.
