So I'm starting to think Stealth Armor Systems might have some underlying questions. They've only got two active NIJ certifications, the one for Hexar "Titan" went inactive a month ago but they are continuing to sell Hexar. Granted, this was raised by the Ngroat guy that runs Safelife (which infamously got into a big pissing match with Stealth years ago because they both sell flexible rifle armor), but what he's saying here is factually correct so far.
What certs they have are for soft armor, which as per >>63988000 some people aren't getting their orders for. Again, reddit, but you take what you can get.
I also ran Stealth's address (1306 FM 1092 Rd, Missouri City, TX 77459), which is mixed use commercial. Nick was wrong on that one, although I don't see SAS' sign on any of the doors. I'll wayback it later.
Shit you gotta watch out for with armor is that the competition is cutthroat and plays nasty with each other, so you never know if someone rec'ing you armor is a true neutral, a fanboy, a shill, or a company rep themselves.
