I can't say for sure, but I believe it is a UTG Quad rail on there, but there isn't a name stamped on it. I got this AK in on trade at my shop and the guy trading it in had taken a can of tan spray paint to it, and hideous is an understatement. I had Deke at "Below Me Custom" in Olympia do the finish. It is a Duracoat finish on there now. As far as colors go he said "If you can dream it up, the color can be mixed." To the best of my knowledge Duracoat holds up pretty well. I have one of the DPMS "arctic panthers" which is coated with white Duracoat and I have had it for a little over a year and the finish has held up really well to me beating it up and taking it out coyote hunting a few times.
