You still need a front sight nodog. But some target sights have a front apeture instead of a pin. It gives you a small hole to look thru. You center your target in the hole instead of placing the pin over it. For some people it is much easier to use, helps with target panic if you have trouble putting the pin on the target.

It works great for shooting spots, not so sure how well it would work for hunting though, but I'm sure it could be done.
