I use a 4 legged wooden stool with a small plastic 3 drawer cabinet taped to the top of it. Drawer is full of tools, so it has some weight.
Added some strips of wood to the edges of the top of the cabinet, to make a tray, and put an old dishtowel over it. It's a good place to lay chisels.
In the tray I also have a wedge of split firewood, cut to fit, with a dished out section on the top edge for the rifle to lay in. That brings it to working height. One benefit of the stool as the base is that my feet can go under it when I am working with something there.
It's dog ugly. When I first did this it was just "temporary", until I could get around to making a "proper" support. But I've used it so long now that I've come to appreciate the utility of it, and long since become accustomed to the ugliness. (I suspect my wife might say the same about me!
