I saw some clean AK-74's at a local shop for $399 that peaked my interest. The 5.45x39 ammo is running 5 cents a round cheaper than 7.62x39 for an AK. I'd like some opinions on the rifle, especially from folks who have both AK-47s and AK-74s. I hate to add another caliber to the arsenal, but if it stays this cheap and is easy to acquire, I may have to.
