All you have to do is keep it clean. Granted that can sometimes be a challenge, but you should still be able to pump several hundred rounds through it before getting nervous.
It's biggest weakness is the 5.56mm round. Not range, not enough shock/energy. I prefer the 6.8mm for it.
But it'll still kill you dead, and quick.
I thought the DOD would have done just as well picking the Ruger "Mini-14" platform with a heavy barrel. FAR more reliable for the slackers that won't clean their weapon...or the unfortunate few who had to run 1000 rounds through it without the opportunity to clean.
What's a couple of MOA at 100 meters in combat? Still more accurate than the AK platforms. Just as reliable too.
If you want to be serious about accuracy with an AK style rifle there’s always the Vepr...
