Are PSA AK 105 and 102 barrels 22mm or 23mm?

Considering getting a builders kit and transferring it to a milled receiver. Need to know if there’s a difference in chamber diameters. This info also helps in knowing what type of barrel to use when replacing a shot out barrel as I doubt psa warranty would cover that

I have seen PSA replace shot out barrels before. As for the size thats probably a question for their engineering and they are not on here.

yeah a shot out barrel i would think is covered under the Lifetime warranty. afterall Lifetime warranty means lifetime of the part right.

The warranty is on every product page of the website:
