Actually appears that you have a clasic FN sporter. A fine quality rifle that has become collectible. Rather than remove the sight I would opt for slightly higher rings to maintain the originality of the rifle. Or a scope that didn't conflict. If you do remove the sight don't damage it and don't lose it.
That was my solution to the exact same problem on an old FN-actioned Husqvarna. The scope only needed to be about an eighth of an inch higher to clear the sight, and thirty dollars later we were good to go!
