AR's are no where near as unreliable as ppl make them out to be. Just putting that out there. 1 grain of sand will not cause a malfunction, contrary to popular belief. They do need to be lubed to function at 100%, but I lube and clean all my guns regularly, so that's not really an issue. And AK's are not inaccurate, they just don't have very good ballistics due to their heavy bullet. The 7.62 will have more drop and be affected by wind way more than the .223/5.56 round, especially at +200 yards. Both have their ups and downs and this debate will never be ended. It's like the 9mm/40/45 debate, or the 1911 vs. 45 long colt debate.
