Rear sight on a SxS shotgun

[Patocazador]

I have 2 SxS shotguns, a Pietta and a CVA both 12 ga. that I want to be able to accurately shoot deer with PRBs.
I want to place a rear sight on the rib between the barrels but the rib is lower than the barrel height. I think that attaching a very short rib piece on top of the existing ones will give me adequate height to dovetail an elevation-adjustable rear sight in. Can this height extension "rib" be epoxied to the exiting one or should it be soldered with low-temp. solder?

What are the potential pitfalls of this idea?

I kinda wonder about POI with your rear site center of the rib while the barrels might not be "regulated" at the distance you want.

Was my gun, I'd test it before soldering or drilling holes or some such. A temporary sight back there might tell you all you need to know about alignment. Building up a gob of black epoxy and filing that to shape would be easiest for me, but I'm sure there are other ideas that could be even better.

There is some "magnetic" rear sights for VR shotguns available (marketed to Turkey Hunters).

I might be inclined to give it a try first because as suggested, you may have to fiddle around to get your aim point correct.

My buddy has the 50 cal barrel and 12 ga set for the cva if interested pm me.

Brownels has a lock tight product that modern gunmakers use often to install sight ramps on high powered rifles.
It is black.

Sight ramp, that's the correct term that I was attempting to explain with the "height extension" description.
