I have one of these set-ups that I bought at a discount. I use it for our classes and refresher for me when I can't go to the range. The pretty blue color is not as intimidating as some others. It is a good training aid. Also, out hunter Ed district acquired a set of long guns that cast a laser beam. I believe they are made by Daisey. I don't have that. Now then. a bit more dangerous but you can take a pellet pistol and load a short section of Q-tip and shoot it into a carboard box but yo will have to so come homework on this one. ......
