Its a mind thing. They are fun to shoot, and pretty accurate. As I said in another post, I used to go to the range a couple of times a year. Since I bought a MP15-22 and a STG44 I have been more times in the last month than I have been in the last 10 years. The old saying "shoot more and shoot more often" really applies. Who knows when a 66 year old may need to draw on his shooting skills? Not to mention that you can shoot all afternoon for a few bucks.
