Knoxx used to, but no longer in 20ga. I saw two new black 20ga stocks in the original packaging for sale somewhere within the past six months (can't remember where) and the asking price was $180 each. They didn't last two days and were sold. Finding a new Knoxx Blackhawk 20ga adjustable recoil reducing stock is a challange, that's why I gave up and bought the 12ga for $78 with the adapter for $17. It looks great and works as advertised.
