I designed and built this one a couple of years ago.......

It cost me about $25 to build and works great. Prior to welding everything together I cut holes in the tubes so that they were all interconnected, and I fill it with water....This really absorbs the recoil...When I finish shooting, I just dump the water and take it home.....
I secure the butt of the gun, and the front forestock, run a shoelace or parachute cord thru the trigger and pull the trigger...Eliminates any human error......

Has 3 adjustable rods, one on each corner, so that you can adjust it to be dead on target at 100 yards......
Not designed to be a portable, drag around with you type rest for shooting gophers, but is awesome when you are trying to sight in your rifle or get true groupings of new handloads....
I was gonna try to patent it and make my millions, but haven't got around to it so I thought I would share it with you guys.......

If your are a decent welder you can build one in an afternoon......
Heres the measurements of the plan....I also have other pictures if you're interested......
