HI Hristo
This plate that needs removing and having a 1mm hole made in it, Is it like a very thin piece of plastic in a squashed t shape with a square window in the middle?? i have mine apart right now and the think looks more like the ares have just got a black market pen and coloured in the led and then scratched a bit off to allow the led to shine through
My laser adjustment isnt too bad and i have a green laser that i am thinking of tring in the slot if its small enough
