When did an AK-47 develope a greater effective range than an M-4?
It's not the AK's that are the problem. The problem is the RPD and similar series of machine guns that are chambered in the 7.62 X 54R cartridge. They have a much longer effective range than our M4 rifles.
The Druganov series of 'precision' rifles are also chambered for that cartridge. While they can't hold a candle to a bolt action platform in terms of accuracy, they're plenty good enough to engage our guys outside their envelope of effective fire.
