I have had good luck with Accu-riser.

They come in black and wood look. Each one comes with a rubber insert for two heights. I use the lower one on shotguns. It seems to work well with old shotguns that came with too much drop without any further adjustment.
The Accu-Riser comes with a strap that runs through the slit you see in the pictures and runs underneath to the opposite slot. Due to the shape of Butt stocks, the riser will move forward from recoil after a while and of course that is a problem. You need to figure out how to attach it properly. I have tried glue but that is a problem when you take apart. Double sided tape seems to work. An added strap in the back should work too.
The advantage to this set up is the narrowing shape toward the top. For me, it does not change the cast from the original location as the Beretta and many others do. I have used it succesfully on several guns. Keeping the cast unchanged is very important to me.
Should you buy one, to protect the stock wood, I sand the inside ridge running along the saddle shaped plastic that contacts the wood.
