Mike. If you are referring to the rail on top that appears to be screwed on, then you won't find it particularly easy to remove and replace with another rail of your choosing. Those screw heads that you see aren't designed to be backed out. The RWS Diana rails that I have are spot welded from the underside necessitating dissasembly to get at. More trouble than it's worth (unless by necessity should your rail shear off like a 350 mag of mine did).Unless your rail has some discernable moveability I would recommend living with it and attaching a suitable adaptor like the UTG bases or the B-Square 17021.Yes those add on's will raise the height of the scope some but you can easily add a cheek piece to the stock's comb to elevate your fit for a better cheek and eye alignment and more comfortable natural sight picture.
