hey i got mine too, but when i got it the rear sight had come off(someone else also had that problem too) and i found an extra screw, but i don't know where it goes. it shoots fine w/o the screw, but still i'm worried. BTW: the screw uses a tinny Alan key instead of a screwdriver. also i live at the beach so everything, i mean EVERYTHING, that can rust will rust. i want to remove the powder coat, but will the ano rust? or not?
