I've recently acquired the MKA 1919 Match Pro 12g, it's the AR style 12g. I'm trying to find the stock adapter that allows for the AR/M4 style buffer tube and stock. I've seen a few when I goggled it but those companies aren't currently making them. Figured I'd check on here if anyone has a spare adapter they don't need and want to sell or a the dimensions of one so I could get it machined.
