Here's the rattle can (spray paint) job I did on my AR in multi-cam. I cut the patterns myself and layered the colors one by one.
I'm pretty happy with how it turned out. I wasn't looking for anything pristine because I'm pretty rough with my AR.
Range test turned out great. All the masking held up and she operates the same. Some of the paint is pretty thick, I'd probably go with a lighter coat for the first few layers next time. I'm going to do a test run on a coffer mug in Kryptek next.
