I have a thread adapter from Krebs but my FSB does not have a detent so what is the best for me to attach the adapter and brake?

I'll have to check to see if that is the case when I get home but I think I would have noticed it. Would it be possible to drill holes in the FSB and adapter for a detent?

Many of them you can't see at all. It's possible to drill a new one, but it's not something I would attempt with a drill press.

For now loctite is working though.

Posted: 7/10/2012 4:40:26 PM Loctite, even the red stuff, will eventually lose its grip after it gets very hot. I know red is specifically high-temp resistant, but I've tried it before and it always fails in time. Think about how hot a barrel, especially the muzzle, of an AK gets from shooting on a hot day. It's more than hot enough to cause the red Loc-Tite to pack it in. I used a crush washer on an old MAK-90 and nothing ever loosened up.
