Does anyone know of a place in the RDU (North Carolina) area that threads AK barrels?  I'm looking to add a muzzle break...any help is most appreciated.

Thanks...

Edit to your title for clarity. dryflash3

you could ask in the EE if anyone is willing to rent their tools and do it yourself.

Just a thought.

If your'e planning on threading that Mak90, make sure you have enough meat on the end of it to thread for a 14x1mm brake/flash hider. Check it with a good dial caliper and you must have .546 -.551 of "meat", IIRC. If not, you can opt for a 1/2x28.
These are pretty easy to do yourself.

Thanks for all the input.  Given all the research I've done, input from the AK Kommunity, I think I'm going to do it myself...just need to pick up a threading die @ CNC.
