I shot this photo at an open day a few years ago:
As you can see, there are four different shades of green furniture on the C7A2 in the photo. The CADPAT cam mesh thing in the background is pretty much the same colour as a brand spanking new set of CADPAT combats (I mentioned this to give you a reference point for the colour).
It's also worth pointing out that the rifle does not have the ambidextrous controls or the extended charging handle latch. The is proof that the modifications were not universally implemented.
I believe this rifle was 'owned' by the PPCLI (that's what I was told). It was photographed at a Calgary Stampede display put on by members of the Calgary Highlanders, KOCR, LdSH (RC) and the PPCLI.
