Can body armour stand up to an assault rifle? Can a ceramic plate not shatter against the bullets of an AR-15 and AK-47 hybrid weapon? Demolition Ranch investigated by shooting the crap out of the body armour to see how long it takes for a bullet to pierce and penetrate through.
He used an ARAK-21 XRS gun which is a hybrid AR-15 and AK-47 to shoot at the ceramic body armour. The body armour has a ceramic layer that is supposed to break up the bullet and a composite layer of fabrics to theoretically catch the bullet. It took around 8 rounds to finally penetrate the armour.
Body armour works! To a point.
