Knight's Armament USGI Rail Adapter System KAC RA 6.25"

Description

KAC RAS rail system.  The listing is for a complete KAC RAS new old stock rail system.  The set will include at least 3 – 11 rib panels and either a 5 or 6 – rib panel, vertical grip and vinyl pouch.  Does not have the original instructions.  I will include a set of instructions I printed from the internet.
New old stock.  No shipping outside of the US.
RAILS IN THIS CONDITION ARE BECOMING VERY HARD IF NOT IMPOSSIBLE TO GET.  I HAVE ONLY A FEW OF THESE LEFT.
You will probably need a delta ring tool to install this rail.  It will make it much easier installing it if you have one.  You can get on on amazon for .89 or on ebay for around .00.
