Buying a modified SKS bolt

[u/BreadHumble8213]

I am looking to modify my SKS with an AR15 magazine adapter and was wondering if anyone sells already milled SKS bolts for AR15 magazines so I don't have to go get mine milled at a shop or attempt to do it myself

Also, has anyone got there bolt modified and can give me a rough estimate of how much it costs?
