I don't know about now, but years past, when SSS used *fiberglass* stocks from Stockade Gun Stocks (Chadron, NE) they eventually ended up at loggerheads. After several rounds of B.S., Lisa @ SSS told me to call Stockade, because "she didn't know why it wasn't ready yet". When I called the guy @ Stockade, he was pretty entertained by that, and said that he'd never even started my order (despite claims that it was 'almost ready to paint') because SSS was deeply delinquent in paying him for stocks that had been shipped. So I had to start my order over with him, and surprise surprise, it was completed and shipped in a timely fashion.
About six months later was when SSS suddenly started making all their own *laminate* stocks... which looked like direct rip-off copies of the Stockade models at the time. Guess someone figured getting a stock duplicator and doing it themselves was cheaper than paying a third party for stuff already delivered.
