We know you are using the shotgun to shoot things, we were wondering what specific application(s) you had in mind. It's difficult to tell whether you are trying to be witty or sardonic over the internet, so try not to do that next time.
For most applications, a front bead will do.
For clay sports, you don't really need any sights because you are supposed to be looking at the target. The bead just serves as a point of reference.
For tactical applications, i.e. home defense, well....a front bead will also do.
For the price of a good ghost ring sight + installation, you might as well buy a shotgun that come with a ghost ring sight. Or buy a barrel that comes with rifle sights.
If you really want to add new sights on your shotgun, I would recommend truglo, hiviz, or XS sights. If you have the extra cash, send it to Robar, Vang Comp, or Wilson Combat.
My experience with aftermarket sights is that they serve better as training tools.
When I first bought my Wingmaster I had difficulty shooting with both eyes open and figuring out if I have shouldered the gun properly, so I bought a hiviz fiber optic front sight. After a few trips to the fields, I decided that it hindered me more than it aided me, so I took it off. It did help me though, so to me, the $18 was well spent.
If you are planning to use this gun, a pattern board and an assortment of shells will serve you better in the long run. If you just want it for mall ninja looks, ATI products will be just fine, as long as you don't use them.
Your results may vary from mine. Good luck and safe shooting.
