Looking for input on 7.62x39 barrels from those who have them

Hey folks,

I'm thinking about putting together an upper in 7.62x39 since I have so much of the stuff. The rifle would be primarily used for pig hunting in this configuration. Those of you who have such a beast, any feedback on your barrel(s)? Price isn't a major consideration, but accuracy is; I don't like them to suffer any longer than need be.
