Yes, I have one that I hunt ut of a lot. It is going up this weekend. I will take a picture and send it to you.
Basically, where the ladder stops and starts to curve, using u bolts we extended it with steel fencepost railing. We made a removeable piece that connected the two which became the shooting rail (we padded ours). We also braced it from about the top of the extention to the back of the seat(by the tree) with very small angle iron.
Hope this helps, I will add a picture as well.
