OK I recently acquired Army Issue, hardly used, Interceptor Body Armor. Has all ballistic panels (protection from 9mm and fragmentation), but no SAPI plates though. Its in Woodland camo, size medium, Date of Manufacture is 01/2004. Just wondering how much is it worth?? I am looking at getting SAPI plates for it but was still wondering the value, just in case I wanted to sell/trade it.
