Mosin Thread Adapter

This is a thread adapter to put threads on a Mosin Nagant without removing and threading the barrel. It gives a Mosin a typical 14x1 LH thread with an AK style retention pin meaning it can use any 14x1 LH AK brake. It pins to the barrel and has a cut out for the front post. I tested it on a model of a Mosin I made from my own and dimensions from 7.62x54r.net. I made this at like 1 am after being frustrated I couldn't buy an adapter that met my requirements. I have no idea if this would actually work, though I don't see why it wouldn't. If anyone knows how to cast steel, I'd love you forever if you made me the casting and shipped it to me. I can't find anyone online in my 20 minute search that's willing to do one off parts.
