Here is a very inexpensive way to sight in a rifle, Vise $ 50, scrap plywood free, 2 wood horses (blue supports) $10 each and a chair. Most people now charge $ 50 to sight in a rifle. I found the plywood a bit flimsey. Might need some 2x4 to brace the plywood. This was my first time using this set up and I did both rifles.
