I am taking my 7 year old gun hunting for the first time this year. We will hunting out of a 5x6 box blind. We have have practicing shooting off of a bench and bipod, but looking for any suggestions or ideas anyone has for a rest for the rear of the gun. We can rest the front of the gun on the window sill. Any suggestion or ideas would be appreciated. Thank you. One thing I was considering is a Bog Pod Death grip, but I'm not sure how it would work in a box blind.
