I'm looking for a survival/bug out type weapon and I have been looking around at 7.62x39 rifles and of all of them these two came out on top: the arsenal sgl 21 and the ruger mini 30 tactical, Now I'm stuck.
Disclaimer -- I like AKs, within the parameters of their specific pluses and minuses. I've owned several along the way, everything from a Century (so-so) to a Krebs (superb) and still have the Krebs. An AK may not be my idea of a perfect 100% solution, but I'd feel well armed with one that didn't have mechanical/QA sort of issues.
That said, I think part of the answer to the question is to better define what the OP is looking for in a "survival/bug out type weapon." For a weapon one might be slinging over a shoulder and carrying around for personal defense during a Katrina-type disaster and/or civil unrest, I think the AK carries a lot more cultural baggage than something with a pretty conventional rifle profile. For better or for worse, the AK profile is associated with basically every significant group of bad guys to come down the pipeline in the last six decades -- Viet Cong/NVA, generations of Middle Eastern terrorists, tin pot dictators, Osama bin Laden, drug gangs, North Hollywood bank robbers, etc.
Objectively, a gun is just a gun, but I'm willing to bet that if you interview a random sample of average Americans, police officers, and active and reserve military personnel (all people you might have encounters with during a bug out disaster/unrest scenario) you'll find a bias against the AK -- probably a subconscious one most respondents can't quite put their finger on. That bias, however, could very well have a significant impact on things like encounters with law enforcement and the military in tense and volatile situations.
The same might tend to hold true with other evil black rifles of different flavors, but I think, for instance, it would not be as pronounced with something like an AR -- which is more familiar (Walmart sells them, for Gods sake) and is associated in the public imagination with our guys, not the bad guys.
