Yes you are right, it is a very accurate gun. I got it when I was 12 and am now 26, havent shot it for about 3 years till yesterday. I learned to hunt w/ this gun and when I was 12 yrs old I could shoot pencils in half at about 20-30 yards w/ no scope.
I found it through their online store. Heres a link.
