Not all 602s came with the pop-up sight. The ones that did had a recess milled in the rear action bridge. Before trying to buy a sight, you need to check whether your rifle was milled for one. Also there was more than one type. Some had two springs and others only one.
G'day @Ark. Trapper. No disrespect intended. Because the 602 that featured the pop-up sight is now quite old, many people have heard of them but never seen them in the flesh. Many I've spoken to have been unaware of how they were set up and others have confused them with the NECG peep which attaches on the rails. Good luck with your search.
