Nope those sights are not going to work with out a rib.

You gotta remember that that little front bed is all that is needed on a shotgun. The shotgun you have is made for one purpose only. Killing people at very short ranges or killing bears at very short ranges. That's it. The barrel has a fixed cylinder bore barrel. Meaning that you can not interchange choke tubes and being cylinder bore there is absolutely no constriction so the shot spreads out very quickly and even at 20 yards with bird shot you may not hit a bottle.

Basically you are wanting to do something with a shotgun that it was never designed to do.


Having said that you got a few options.

Scattergun Technologies makes a ghost ring with front tritium bead that can be installed on that gun. It retails for about $115 directly from them plus the cost of a gunsmith to install.

Option two is to get a Williams guide receiver sight which will mount on the receiver of the gun and get a Williams shotgun shorty ramp of the height you need plus a dovetail to go in the ramp. These will run you about $60 - $75 for all three pieces plus ithe cost of a gunsmith to install.

You are going to have to call a couple of gunsmiths to get a price for your area but I would charge about $50 for the Scattergun sights and about $25 for the Williams sights


Forget about that heat shield thing. Junk.

That barrel will not work with your gun because of where the barrel lug is mounted on the underside. On your gun it is mounted at about 17 inches out so it fits the 7 shot tube. On the barrel on Ebay it is mounted about 11 inches out so ti fits a 5 shot magazine tube.
