This ak12u is an Arcturus already upgraded I had no problems with it. Shoots around 380-390 fps Comes with 2 mid cap mags and a battery and grip. Dm me for shooting vid or if u have any questions! Only 1-800 were made so it can be a rare gun some day. Reason why I’m selling so cheap it’s because it needs a new home and I think this is a reasonable price instead of 400 or 480 No trades pls
