Hi,

I've searched and searched, and I just can't seem to find information on the difference between a threaded and press&pin barrel is for the AK platform.

Specifically, is it something that has to do with the receiver, or does it have to do with the barrel? If somebody were to buy a milled parts kit, for example, would they have the personal option to choose the type of milled receiver (threaded or press&pin), or would it be contingent on the type of barrel included in the milled kit?

And what are the pros and cons of each?

Thanks for clearing some of this up for me!

Has to do with milled receivers.  In Earlier AKs the barrel was threaded into the receiver, later the barrels were pressed in and a pin was drilled.
