I wouldn't say that an AR 15 or AR 10 is the perfect choice for hunting in Alaska.
However, whoever thought we would have gotten to the point where AR's would be illegal; but we are nearing those cross roads now.
If you want to own any AR platform rifles I would highly recommend you buy them NOW !!!
Otherwise, I would recommend a synthetic stainless boltgun in 7MM RM, .30-06, .300 WM, .338 WM
