Knights Armament KAC M4 RIS Rail, (used) - Med Grade

Used; both sections are original RIS rails with matching Picatinny slot numbering (1-15 from front to rear).

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 well used, but 100% functional.. Generally Grade B- / C+.  This is Titusville, FL stock.
