I'm guessing those are the "airsoft" glock select fire mechanisms people were getting busted buying off of wish around that time. However, with the ambiguity in the article, not specifying what exactly they seized, and the opaque packaging, those could be anything not 922(r) compliant. Like flash suppressors, which technically would have been "assault rifle" parts not to be confused with "assault weapon" which is a made up term.
