is it constructive possession to own an AR15 with an M4 bolt carrier and also have the 3d printable swift link file or the corresponding t-shirt?

for the record: i do not own a 3d printer, do not own an M4 bolt carrier, and do not own a swift link (3d printed or otherwise) or any other similar device.

i'm just curious about the application of the law by the government. i've no intention of testing it.
