Well?   I need the thread pattern because its approximate the same as the Saiga 12 front sight, which I lost and must replace.  I hope to replace it with an aftermarket shotgun bead, but of course, I would have to pick the thread pattern correctly.   I think all the aftermarket sights are english, and the AK threads are likely to be metric, but with a little loc-tite and ingenuity, I bet I could get it to work.  So help me out here, guys.

I'm gonna bump this because I'm guessing no one who saw it knows.

The AK-47 pattern is 4mm x.75 european, 4mm x .65  chinese.
