I did it myself... have been doing it for some time now on several (actually most) of my rifles.
I just did the same thing on my AAC Micro 7 only without the white spider web.
I start by wiping the stock with a cloth and Lacquer Thinner (lightly) to clean and etch it.
Then blow with clean air to make sure no dust or "stuff" from the cloth.
Paint with the desired base coat (most often Krylon or Rustolium flat or camo paint).
Then the magic...JoAnne Fabric sells the spider-web paint (on line only) and it has to be applied a certain way, but I can do white, black, or silver and do a few coats to desired coverage.
Once it dries, I coat with a simple matte polyurethane spray for a few coats and... WALLA!
I was toying with doing it as a second job... I've done my Sig grips, Blackhawk SERPA holsters and stuff like that as well. I get a kick out of it and it keeps me busy.
Did a Steyr SBS stock once after stippling the grip areas and it was a knock-out...giggidy!
My best was a HS Police stock that you would lose if you set it down in the woods
