Based on the body color fender flares, I suspect it's not a "Mountain" edition grille. They could've been added later of course, but still.
Whatever the case, it's a stock grille with some tidbits added. Unless it's a Mountain edition, it's probably just been painted dark gray. The Jeep logo has been painted black. A bug deflector has been added. "Euro guards" have been put over the lights. Rugged Ridge inserts have been put into the seven slots. And of course you've got an aftermarket bumper/winch with a hoop bar over the winch.
Can be re-done on any jeep by just ordering the parts.
