"smart" - My main points to "kybob": VERY doubtful it was a .50 cal (not mentioned in the video) and it was not a NEW competitor product. Likely was Xsapi ceramic-based plates by Ceradyne or BAE.
Now - re: your point (I think) - You are mistaken...
it was .50 cal AP rounds that were stopped at Dugway by BORK using 1/8" Brinell steel backing, fired from 50'.
It was not .30 cal AP.
Non-ceramic "Fatboy" plates were not NIJ tested for .30 cal AP @ "Oregon Ballistics", so I don't know what they ultimately stop 3 times.
I do know BORK plates were the first ever to stop all 6 rifle rounds in all 4 plates submitted when 3 rounds within deformation standards will get an NIJ cert.
"Bourque's Level III stand-alone Kryron Terminator Armor System demonstrated its industry-leading multi-impact capabilities by defeating all six 7.62x51 FMJ NATO rounds within the standard 44mm back face deformation standards. Bourque reached this performance milestone on all of its Level III body armor panels tested.
Kryron Terminator Armor also provides additional advantages over competing armor that are essential for the survivability of law enforcement and military personnel. Terminator armor eliminates ricochet and spall -- shrapnel from the bullet and armor, respectively -- because Kryron armor works by catching bullets instead of shattering and deflecting them."
