I have a black NATO length K-var polymer set for a stamped receiver that I purchased from Cabela's. It has the metal heat shield in the lower forearm. I installed it on the rifle and went to the range once, then I decided to go a completely different way with the set-up.
Here is the link to the page at K-var's site that shows the stock set. Link
I will let you have it for $75.00 (Postal Money Order) shipped if you are interested.
