Steel Ballistic Plate Level III+

Steel Ballistic Plate Level III+




For a standard carrier you will need two plates.


Our Steel level 3+ plates are made out of AR500 steel with a padded front and back and are rated to stop up to .308 as well as all intermediary calibres including m855 and armor piercing 5.56 and 7.62x39. These plates are our most affordable option. These plates do not come with a thick layer of spall protection and therefore the spall is a factor that you will have to consider. Our Steel plates are single curve, Shooters cut, and multi-hit rated. They are 7.7 lbs per plate. These plates are 6.3mm thick and are 10x12" which will fit any plate carrier designed for a 10x12 or a SAPI Medium.
