Nice product - Vltor RE47 AK47 Receiver Extension Modstock Adapter Aluminum Black

This extension was easy to install. I did have to to file the corners down on the rear dust cover but it was no big ordeal. They include 3 with the stock, they are plastic and easy to file if any fitting is needed. I'm knocking off one star due to price. I know it's a specialty item but it seams like it could come in under $70. I may kick myself latter for not going with the Magpul Zhukov folding stock but for now anything beats the standard AK wooden stock.
