A missed opportunity. You should have pushed Ghetto Blaster a lot harder. It's time to make that moniker official.
Few are rated to stop direct hits from even pistol bullets, pretty much none that you can afford and comfortably wear are going to stop rifle ammo. They're more for protecting the face and eyes from fragments and thrown objects, which is still important. Remember that more soldiers were killed by artillery and bombs in both World Wars than b y small arms fire. Rocks can be nasty.
