New old stock, I have one left. See manufacturer website for more info, these are the “B” configuration, so the largest kit they offer. Single level of armor, with 11 gun ports. Can include additional plates to double the armor providing an increased level of protection for an additional fee. Outside dimensions are 116”x72”. Manufacturer states these can be setup by 2-3 men in under 15 mins (it took us a little longer). Local pickup in Macon, GA.
