I used some self-adhering cammo wrap to hold some segment together. It goes on in minutes and seems to cover pretty well. I still need to make a defuser for my scope objective lens and I may paint the rifle a color other than black to help blend in, but I am pretty happy so far.
From the front and side with my Nikon scope.


The cammo wrap is 3 sections. Front, back and optics/center hood.

Here is is with the EOTech and magnifier. Works pretty well with all of my optics.
