AK muzzle adapter

[Dirtball]

I'm looking to put a .308 muzzle brake on my AK. In my haste I neglected to check barrel size before ordering and while waiting for delivery it hit me and I was correct, it's a bit large. Sooo....who makes a quality adapter to go from 14-1 to 5/8-24 thread? Spikes Tactical makes a few but not the conversion I'm looking for.

Oh and since I didn't mention it, the barrel in question is not currently threaded, that's one of the reasons I went with the particular brake and thread that I did.

YMMV Muzzle brake adapter for non-threaded barrel - AR15.COM

Then again this guys talks about losing an nfa item in the process. Under reviews

Thanks for the link but as usual I asked the question before I searched it myself. Those set screw muzzle adapters seem pretty sketchy to me. I bought 2 Krebs Custom adapters that should do the trick. There was also a 2011 thread from the INGO in my search results, I tried to get in touch with one of those companies but nothing came of it.
