I did not take the time to read through all the posts in this thread so I am sorry if I repeat something that has already been said. I currently own both guns and from a reliability standpoint the AK-47is far superior to the SKS. I find that my SKS using surplus ammo is prone to jamming every 5 rounds or so. The internal mag has been adjusted many times and I have tried many different aftermarket detachable mags and still run into this problem. The AK-47 on the other hand is one of the finest assault rifles I have ever run across. its not nearly as accurate or flashy as many of the other rifles in this category but it packs plenty of punch and I a situation where your life counted on your rifle performing I would want an AK-47.
