Beretta & Benelli Stock Reducer, 8 OZ. (For Wooden Stocks Only)

I have these on my 391s and A400. The work. These is something about bolting directly on the stockbolt that dampens recoil better than just using weight In the stock. You can feel the mercury sloshing arojnd but not when shooting. Use a split ring lock washer to keep it from coming loose, and a touch of blue locktite. Graco makes a similar product without the mercury, which is less money.
