Yeah that’s what I found too about the investigation. But nothing about a date or prices on them. Then some videos of guys testing them out very light weight plates for level 3 but they seemed to hold up to 223/308 rounds.The PC is around $150, +/-, and the extenders another $30, and the placard/mag carrier maybe $30, so so around $210 for carrier and accoutrements.
I can't find any price info on the plates, but I did find info that the company was under federal investigation.
