I recently did a little cleaning up in the basement, and had a chance to formalize the area where I do some airsoft. Using garage door screens, I lined an area 8' x 25'. I set up some box targets and three rows of TacTrainer's metal targets, scaled for steel challenge and IPSC stuff. (I just use one row at a time, and set the others along the side of the range.) Unfortunately, I don't have any place for the chairs, so I have to live with them down the sides. The metal posts seem to be a problem, but you get so you don't notice them, and they are almost perfectly positioned at 15 feet for barricade shooting!
