Theres not much to say here except my 18 stopped wokring. My friend said I could fix it, it's something in the lower(the knocker not hitting right or something). So if you can fix it and want it or you want a perfectly working upper tell me. I'm not sure how much it's worth. But this gun has been A LOT. To be honest it probably has more BB's through it than any of my AEGs. So somehwere around I'm guessing maybe 8,000. Or I'm over guestimating. Anyways, you get the point, broken lower, used but perfectly working upper.
