Threaded barrel or threaded FSB?

[leadchucker 12]

I see AK muzzle brakes that screw onto 14mm threads on the barrel and are retained by Loctite or by a crush washer. And I see muzzle brakes that screw onto 24 mm threads on the FSB and are retained by a detent pin.

 

After reading a lot about it, I get the impression that the correct AK 74 muzzle brake mounts on the FSB. And yet, my '09 IZ 132 has a military barrel, and it is threaded. So which is more "correct" for an AK 74?

 

Is it possible or practical to modify the FSB on my IZ 132 to take the 24mm brake? (BTW, I do have a mill and a lathe.)

I'm under the impression there is a thread adapter plug you can put on your 14mm threads that makes it a 24mm, which I believe is more accurate to an AK-103 design.

I just came across these looking for options for my 223. Seems like an interesting option, because you can swap around between the 14mm and 24mm devices. Also, one of them looks like it might work if you were to thread all the way back to the front sight base.

 

I wish I had the spring and plunger in my FSB.

 

Has anyone used any of these thread adapters?
