Hello All,
New to the forum and was recommended by a friend. I am interested in potentially purchasing some Level IV armor and am pretty new to this topic. I have been educated on the difference between NIJ certified and NIJ tested am trying to find what best suits my needs...
I recently came across this NIJ document dating from 1971 containing two Level IV ceramic solutions from way back in the day, which are the AVCO PA-500 and the KT-1. It's quite interesting to see how far the industry has come since then. The document sure makes for a good read...
