I have a few Saigas and would like to start threading the barrels to install devices. Saigas have a cover that is part of the FSB that covers the end of the barrel. I plan to dremel this cover off and thread the end of the barrel.

I have read that others have tried measuring their barrels and that they are slightly smaller than 14mm in diameter, making it near impossible to thread to 14x1mm LH threads. Can anyone confirm this? I'm hoping that they are really 14mm in diameter. What is the true diameter of a Saiga rifle muzzle? Thanks for any help.

Someone just let me know that their Saiga barrel measures out to be .565" or 14.351mm. Do you think this is close enough to work with a 14mm LH die? Or will I have to find a way to turn down/sand down/grind down the barrel closer to 14mm to get it to work? Thanks for any help.

14mmx1 LH (fine thread): Standard AKM thread size for threaded barrels.
The minimum diameter of the threads is .5118" - approximately 13mm (12.9997mm). This size requires a barrel diameter of at least 14mm or 0.551" to achieve a proper thread depth of 75%. Less thread depth may require permanent attachment of the muzzle brake via silver soldering.

In short, "yes" you have plenty of diameter to work with.

No, I have been told by others than you can easily thread thicker than 14mm if you use an adjustable die. You just have to start shallow and then tighten up the die and go deeper.
