Just sayin'.
I recommend that you UPS, Fedex, or USPS the upper to avoid the issue.
If flying I would disclose it, making it clear that it is not a firearm but parts. It is likely to be identified as a firearm and pulled for further screening if not disclosed, potentially causing unnecessary delay. If you could enclose it in a small, hard-sided TSA compliant case with locks so much the better, just to avoid issues.
