Hey Duke, my "opinion" is to go with the SKS. I have seen too many problems with 762X39 uppers that others had. Broken bolts, lite primer hits on Russian ammo, and just getting lucky to find mags that work properly. My SKSs always work, and I have one that will consistantly shoot 2" a 100 yds with Barnal ammo. I love my ARs and shoot them a lot, but the SKS is my favorite 762X39 launcher.
