I think most parts dealers refraing from selling complete bolts to keep prevent headspace problems from occuring. If a 700 bolt will work, they are easier to find. You would have to allow for the curved 700 handle in your straight 722 slot. Somebody with more knowledge than me will have to answer that. I do know a 700 bolt will fit in my 721 BUT THAT IS FAR AS I WENT WITH IT. Maybe a gunsmith or Remington authorized repair center can get one?
