break the gun down, clean the paint off with lacquer thinner, buy a cerakote kit and do it yourself. To get the upper, lower and handguard/rail done would be in the $200 range to start. If they have to strip it, or if you want multiple colors or camo patterns it will be considerably more. Pretty dont make it shoot better. Do NOT cerakote the inside mag well or inside the upper or lower, you will have problems.
