I recently acquired a part-swapped Luxe that I'm not entirely fond of.
The dust black frame and regulator sleeve were swapped for dust white ones.
I would like to now swap:
My DUST WHITE FRAME/REG SLEEVE
For your DUST BLACK FRAME/REG SLEEVE.
If I happen to run across the Luxe that mine was swapped with, I would also go ahead and swap the feednecks as well, if desired by both parties.
