Thank you very much for the info, pal. Sounds like there shouldn't be a problem at all. I too love the benefits of an AK in 5.56. A few friends criticize my "AR-47/AK-15" tendencies, but my response is this: I paid $600 for my AK about 2 years ago straight from Kvar. It's 100% reliable and it can hold its own, accuracy wise, against a number of ARs out to 400-500 yards. For another $100 or so, I can buy the AR mag adapter. So after about $700-800, I essentially have the equivalent of a piston-driven AR ... and how much do those generally go for? The uppers alone can go for as much as $1500! So
