A lot of great recommendations on this thread, some I was considering and some I was not. Certainly more to think on. I will not be doing any hunting - and should I *need* to hunt, much less have the ability to hunt in my current location, the situation would be so dire that it wouldn't matter what the regulations were. I will mostly possess the rifle for my own enjoyment, for shooting at the range and plinking.
But my justification for purchase are philosophical, political, and tactical. I believe in 2A and all that it stands for. I believe in my right to defend my own life. I think that the battle rifles with the most legacy and historical precedent are probably the M1, The AK Series (47/74), and the AR15/10. Steyr and FN are probably close to the AR, although I think the M1 and AKs have them beat - so it's not surprising that a lot of suggestions mirror this.
Assuming I went AR in my current location in a very urban environment, I'd probably be better with a 10.5 or 12' barrel, but would still opt to a 16' to draw my ranges out 200-400M. I also would not plan to stay here if the situation was untenable. That's not to say that I haven't been considering other things : in fact an SKS was fairly high up on my list for its well roundedness.
If all I ever wanted to do was shoot on the range, I'd spend 4 to 600 dollars and be done with it. I'm willing to spend a little more to get something reliable. I'll spend the time with my system to gain the skill required to put the rounds where they need to go, I'm a fairly experienced shooter by my standards (not by many of the people on this board though). Larue's are nice, but a bit too pricey by the way! And I still haven't even close to made my mind up....AK74/47, SKS, AR15/10 of various brands, FN, etc. The suggestions so far have been good - and I'd love to hear any refinements now that you know.
