+1 on the assessment of the AK platform. I also own an AK and this is after owning an AR. Frankly, I got a bit tired of the meticulous cleaning that was required and the frequent jamming. Bought the AK and after literally thousands of rounds, it has never failed to fire. And I've shot some junk ammo through it and it just keeps on firing. Is it as accurate as an AR? No way, but it never was intended to be a match rifle. I like to refer to the AK as an 'area denial weapon'. Also, it seems to be the luck of the draw at getting one that is accurate (as much as a 60 year old design can be). Some are just better than others. I was fortunate and got one that will easily hit a 8 inch steel plate at 200 yds, round after round. For an urban combat rifle, that is accurate enough for me.
If you don't have one, I'd recommend picking one up just for the fact that it really ticks off the liberals. And that is always a good thing. As with most of the surplus weapons available today, the fire control group seems to be the weak link. When I first fired mine, the disconnector was not right, and I emptied a 30 round magazine in less time than it took to read about it. Fortunately it was on a military range and all anyone wanted to know was 'can I try that too?. Replaced the trigger, hammer and sear and it's all good now. Crisp trigger pull and no more chance of a visit from the ATF (Washington state is a no Class 3 state). With a quality fire control group, you can easily bump fire it at full-auto rate, if you like that sort of stuff. Sometimes I do too. Can you hit anything? Only by pure luck. An AK firing at 400 to 500 RPM is not accurate but sure scares the locals. Not recommended at your local gun range.
IF the SHTF, I would not hestitate to take an AK with me. As the old saying goes 'Ten million peasants can't be wrong.' Providing you have enough ammo it would be a suitable weapon to take along. And it's dirt cheap to shoot. Only a .22 cost less per round.
