Ok I have just boght that gun. It is a very nice gun. In the box you will find 1 hi cap 300 rd magazine, booklets and such, one 8.4 volt mini battery, one charger, not with a discharger, a cleaning/loading rod, and a black tip that you can switch out (im not sure how though). The charger they give takes about 6 hours to charge one battery.
As for the site, that is the best place you could possible buy from. I had a wonderful experience with them, and better yet my order was precisely the way i wanted it and it arrived earlier than expected. PM me if you have any ohter questions about the gun i will be more than happy to help!
