Dating from November 2006, this Colt Defense LLC patent for a “Modular Firearm” covers an M4 rifle with a magazine well that “may be replaceable and removable such that magazine well may be replaced with a different magazine well to change caliber.” There are a couple of other gems in there as well so go take a look.

Thanks to a sharp reader for the heads up!
