Im going to go out on a ledge and say no. Lauer will match most color swatches you send them, UNLESS the color is unstable at higher temps. Some coatsing will literally change color as they heat up as they change on at that sciene level shit. Im no scientists or master chemist, but Lauer, KG, NIC industries all try to provide a FDE variation, but everyone (from what Ive seen)has a specific Magpul FDE, because magpul aftermarket nitch. Now unless your completely uber OCD or its that important, FDE (slightly darker) vs Magpul FDE.
I would, and have many times, call them, talk to any of the Techs at Lauer. They can give you a better understanding then some dude on the forum. They are always, more then willing to help you find what you need.
Just look at other gun coating manufacturers and see they offer many colors, and will often have many in Specific Magpul flavored color. The colors can very drastically from what you may be thinking. Take a Magpul OD Green and Military OD Green from KG Gunkote. I have used both. Magpul OD comes out more tan/green where the mil od is almost brown/green.
