If my memory serves me right they are a Mercury Device

Sounds like a fancy name for a recoil reducer,my new Stoeger M3500 came with a weight that screws onto the bolt that the stock is attached with.Mercury filled recoil reducers are available to take up some of the force of recoil by liquid absorption of the force,maybe a search of recoil reducers would get you better results.

I have a 6 oz. Staub mercury recoil reducer in the butt stock of an 870 TA. I also have several Edwards 4 oz. mercury recoil reducers in the butt stocks of various 870's.

Eith the Staub unit or the Edwards unit is simply a closed cylinder containing mercury and some type of mesh that impedes the flow of the mercury upon firing.

Once in the stock, you can shake the gun and hear the mercury sloshing around.

These devices do reduce felt recoil simply because they add weight to a gun. Maybe the liquid mercury helps, maybe it does not.

There was a man named Jimmy Johnson (AA/27) who sold them at the KY State Shoot. My 6 oz. model for an 870 cost about $75.

I have seen Staub units that attached to the front stock and/or under the barrel of break action trap guns.
