When you first mentioned an adjustable stock conversion in another thread, the first name that came to mind was Jack West. He's was known as the premiere guy to do adjustment conversions, so I checked out his web site to get an idea of his current price schedule. Imagine my surprise when I found no mention of the custom work, Jack is now doing adjustable synthetic stocks. The circle become complete when I found Speed Bump in Jack's links. They sell the Jack West adjustable stocks.
