Level 4 Plates

NIJ Level IV Plates provide the highest level of protection out of all of the NIJ levels. Plates found in this category are capable of defeating military armor piercing rounds as well as bubba's hunting rifle with his pissin' hot loads. These plates will stop rounds such as M855A1, .30-06 AP, 7.62x54R AP, .22-250 SWIFT, M193 and M855. 
If you need the highest level of protection, level IV plates are what we recommend picking up.
