I shoot pellet guns in my basement. I picked up a .22lr rimfire bullet trap and lined it with Duct Seal: http://www.homedepot.com/p/Gardner-...d-Plugs-10-Pack-DS-110/100212441#.Ur_0CPscOSo
Pellets penetrate into it and then just fall out usually. Quiets the trap way down, too. Not sure if the airsoft will stick into it or just fall off or bounce off?
