tldr
>Against actual rifle threats the 6.5mm titanium plates would only defeat 556 m855 at 100 meters. It got lol penned at 3.6 meters in video by said m855.
>If you are stuck with a vest using 1.24 mm plates you need more then 600 meters against 5.45 7n6.
>Only the 13mm boron carbide plates have reliable rifle protection against 556 at a distance of 10 meters and it actually outperfoms stated distance since in the video it stops m855 at 3.6 meters and later M855A1
