One of these annular cutters will size the barrel muzzle end down to to use a 1/2” or 14mm die...

That would work to cut the barrel down if I was slightly over. It is pretty close now. The problem I run into is the pilot for the die cutter in 1/2x 28 is far too small for a 7.62 barrel and doesnt properly line me up. My 5/8x24 pilot fits the barrel perfectly but the barrel was cut down so far when they ground off the threads the die side right over. I will try to take a picture. |

The barrel was never made for 5/8x24. The standard AK thread size 14x1 LH. 14mm requires a roughly .550" OD on the barrel. These are standard AKs with a couple of operations like the third hole and barrel threads left incomplete to comply with US standards. |

Both sets of digital calipers have grown legs so it will be a couple days before I can take an exact measurement of the OD

I have the .550, well. 549 but it looks like I can thread it to the original thread pitch. Thanks for the input. Noe for a new die and guide |
