The "true" OG 'rail, the Knights Armament Company RIS is the big brother of the KAC RAS.
At Charlie's we build a number of rifle uppers with KAC parts. Our inventory of new old stock is divided into two groups: The stock that we use for builds and the the stock that is vintage, and often made in Vero Beach, FL early in the life of Knights.
This rail is new, but may contain very minor cosmetic handling marks. Generally speaking, expect some blems that would be under the rail covers, and some small scratches on the anodizing. Very near new quality, but has been handled and historically not with the same care that we package these at Charlie's. Generally Grade A, A-. This is Titusville, FL stock.
