I have an 05 Zshotted systema PTW. It was upgraded by ZSHOT and sat in a closet for a few years. The electronics and motor were upgraded, but I need to pull it apart to verify if they are the newest or the previous gen. Gun shoots great and works as it should. Really looking to swap for other cool replicas, or high end HPA stuff. I don't want your speedsoft stuff, polarstar jacks, or infernos. Message me and we can go from there.
