Did you talk to 1biggun? He did some, but he's also been busy with a new job too.
You can check out Parabellum Combat Systems in Stilwell OK. Talk to Jeff. He made me a barrel for my MP5 in 7.62x25.I'm building an AK in 7.62x25, and need a barrel. Let me know if you have/can make one so we can talk price.
