That's hard to do when you have to stand in a box and use ear plugs. I even impressed myself with the head shots on the poppers behind the barrels. In Front sight I saw that in one event they had a wall with windows where you had to pull the cord to keep the window open while you shoot. I thinking this would be a cool prop for us. i have some ideas on how to build one. What do you think? I also have an idea for a stage with or without this prop but would be better with it.
