If you ever "here" of a manufacturer who has a half-inch tolerance range on a 14.5 inch long part, I'd advise you to walk the other way.
Gas ports and buffer selections depend on certain assumptions about barrel length. BCM will surely swap this out, and needs to know about the disparity.
This isn't an illegal gun, it's an "undocumented protection device". Don't be so insensitive.
