This is a Vietnam era U.S. 1969 Body Armor Front & Back Plates 30 Cal Protective Size Large Long. I have 3 sets left. They are great conversation pieces or for collections. I will sell sets only. Will give better deal if you buy multiple sets. I have tested one and it did great against 9mm and 45 with no backplate deformation. 5.56 did penetrate the plate but stopped in the soft kevlar behind the plate. Will sale or trade. Trade for Canik Rival mostly but will consider other things of interests.
