Things I liked:The gun itself is solid. and shoots repeatably. Things I would have changed:GAMO's customer service. I sent an e-mail regarding only receiving 2 of the 3 batteries required for the laser sight, and included my return address. They replied with my original e-mail attached saying that they wouldn't do anything without a copy of the order showing it had been purchased within 30 days, and to provide a return address as well as a description of the problem. I replied with a copy of the paperwork t, restated the problem noting that it was the same as in my previous e-mail, and included my mailing address again. I also mentioned that the optical sight lacked enough vertical adjustment to fully sight it in; I haven't received a response since. What others should know:The optical sight lacks sufficient vertical adjustment; at 15 feet the impact can be adjusted from 2" low to about 10" low. The quad-rail mount is weakly mounted and flexes easily.
