Saw the other "zeroing" post, however my sight isn't blurry, so thought I would set up my own topic. Basically, I've just bought the below ICS M4A1 from my Dad's friend and it came complete with a red dot sight, meaning the original triangular "sight" ontop of the weapon has gone.
Now I've tried lining up the red-dot sight with a can about two meters infront of me and I've noticed the shot is going slightly lower than I am aiming, but also slightly to the right. Does anyone have any experience with the below red dot sight and how to zero it? I've got it lined up with the iron sights, so I may need to zero them too!
Yep, another Newbie question from me!!
