Markings on 5R Barrel??

[BigMo]

On the Remington 700's, are there specific markings on it to indicate it has a 5R barrel? Or some other way of knowing?

Thanks!

Thanks though........
I got an answer on another site. I guess I was having a brain-fart and didn't realize the 5 part of the 5R referred to the number of grooves. I don't have the rifle in hand and so will have to look that way.
