Based on your reading is the expiry date of ceramic mostly (or entirely) bullshit? And recognize at least in my case this stuff is sitting on a dark shelf or something so I'm not out on tour for five years knocking it around.
That sounds correct.
Sitting in your basement really doesn't cause any wear and tear like bouncing around in a hot and cold truck of a vehicle will cause.
I think the 5years is more for warranty and certification than anything. I think what the manufacturer says is they can't certify them for longer than 5 years. It could just be an NIJ rule. I don't know.


What do they accomplish with banning this though? I don’t recall criminals or mass shooting terrorist wearing these. Only in the movies ..... oh wait all gun controls get their ideas from movies. No wonder John Wick got to shoot his Fully Semi Auto in NYC with a 30 round mag without a permit.
