AR500 armor plates are extremely tough.
Are these sophisticated armor plates tougher than the .300 Winchester, .338 Lapua, and .50 BMG rifles?
These guys test it out, and get some interesting results.
The .300 Winchester magnum did not get through. The .338 Lapua did not get through.
The .50 BMG cartridge did. The solid brass Lehigh Defense Controlled Chaos .50 BMG bullet made quite a mess.
What did we learn from this video? Never get hit by a .50 BMG, no matter what you have strapped on as body armor!
