For a quick-try-fix, get a bottle of white-out, and paint that front sight white. It will stand out much much better, and can be seen even in dense woods. It is much better than a gold bead, except in instances when you might be hunting in alot of snow.
The fire-sights are also great, but are generally made of plastic, with plastic insert rods, and are not very durable. You have to carry extra rods in case you break one. But they REALLY stand out.
