I pulled this thing off an adjustable stock I put on my 10/22 for Appleseed. It fits both TAPCO’s 10/22 stocks and (supposedly) most AKs. eBay won’t let me sell it because it is evil apparently. I have no need for it and would rather not just pitch it I. If you cover shipping you can have it. The customer still has to find their own shoulder thing that goes up.
