Campo I would highly recommend the Tru-glo Pro-series Magnum Gobble dot fiber optic sights.It is all metal,fully adjustable.And I love mine.I am getting another set for my 11-87.Some guns aren't true center from the factory,and you may need a set of sights that are fully adjustable,not just some that clip on.The front bead is also real small,but is plenty bright,that helps to pin-point your aiming spot on longer shots,even better on long barreled guns..Bigger beads,will cover too much of the target area on long shots,making pin-point accuracy more of a guessing game.They are well worth the money.Here's a link to BPS.
