I only have a 4200 4-16x40 on a varmint rifle. But I do have a 2-7x leupold on a BLR. On the lower power settings I can see the front sight but it's not an issue, I've ignored it for over 20yrs. If it bothers you, maybe removing the front sight is an option. The only other option would be to install higher rings, not for me, I like my scopes as low as possible. It may not help that much, anyway, with the FOV on low power being what it is.
