First of all, if you miss at 500 yards, then you are probably just part of that 50% of the population that can't shoot that far. Secondly, if you miss with the AK74 at 500 yards, then you are probably part of the 90% that cannot articulate the issue sights at that range. Thirdly, you may have a gun with a partially shot-out barrel. And lastly, factors such as wind, trajectory, ammunition consistency,etc are now wacking your 52gr bullet. My AK-74 will print 2-3 minutes @100, but wind and such start to play with it at longer ranges. I have a gun built from a new parts set, and the barrel is great. The AK74 needs optics to tell you just how good it is, and to let the shooter do his part.
