Truth is, it depends on price, reciever type, type of round. If you drop enough work and/or money into one, you can get sub-moa results. The 762 39 round is possibly one of the best battle rounds I think, because it's light and packs a punch, and until 2-300 yards, it's perfectly capable of tack driving. After that, you really get drop off, which can be worked around, but and kind of breeze reeealy pushes the 30 caliber bullet around. But if you get an AK in say, 308, with a 1.5 mm stamped or milled reciever, you can do the same thing you average AR10 does. There are AK's in a bunch of calibers now, and if you buy one chambered in 5.56 with a cold hammered barrel from FN, it'll kick the **** out of an AR by being more reliable and matching the MOA. The side mounted optic **** looks like a horrible option at first, but it works, and it works well. If you're really into it, you can quad and top rail it out till it's as Lego as an AR-15. In a situation where I'm going into the extreme unknown for a long long time, I'd MUCH rather have an AK than an AR. Due to it being so indestructible and non-failing, in any environment. The "loose sloppy feeling" in the action is actually tolerances made really loose on purpose. It literally is self cleaning, and can be shot for decades without being cleaned or serviced at all. Dirt, dust, mud, ice, soot buildup can't jam this weapon. You could probably just weld the dust cover to the reciever permanently and slap rails on it that way and not need to worry about having any issues.
