Pardon my ignorance but after doing some searching, it looks like MSA makes the TC4C-2092-LG (level 4) plate. However, I'm very confused and I'm not sure if that information is correct. So, does MSA make the TC4C-2092-LG plate? Can someone show me some ballistic data for this plate? I really want to know what type of ammo this plate will stop and if it's a good buy?
