RE: AR-15 vs. Mini 14 for predator hunting?
They are not even in the same league as far as quality and accuracy goes. I hear the newer mini 14's are better, but I doubt they are better than an AR. I would spend the extra money on an AR or get a bolt action. You could probably get a decent bolt action and scope for what a mini 14 would cost you. And it would be a much beter gun in my opinion.
Not to mention if you get a bolt action or single shot you can pick a different caliber if you want. Like a .243 or 22-250.
