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 is almost as old as Vero Beach, but not quite. Most of these rails are made from 2006 to 2013. Many will have the hex-head screw.
This stock 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.
Note: Included is only the upper and lower quad rail. The rail covers shown in one picture are sold separately.
We also have new pristine M4 RAS' in KAC boxes, etc., as well as lesser quality and Vero Beach stock.
