hello, what size mounts fit the webley sport and can someone please recommend me a decent scope that is under 60 pound?

My brother is very interested in guns, so I want to buy a gun for my brother as Christmas gift this year. Since I don’t know much about that, so I want to ask for some advice here. I found 2 guns on the Internet...

I say "sniping" because i realy mean a form of long range acuarcy shooting competition available to the public (if any one has seen top sniper on the military channel i dont mean that kind of competition ,close, but thats not avalible to the public). I have no idea what kind of shooting sports...
