Airsoft Comp M4 red dot clone raiser

just got myself a vector 3X magnifier, and put it and the clone comp m4 on my 416
the co witness is a bit off (still usable though), so i just draw a spacer for it.

the raiser in the picture is 6mm height which seems 1mm too high, so there's a 5mm version too.

you will need 2 M5*8, 10 or 12 counter sink screws depends on your needs.
