I am looking at all three, it does not seem like mini's are such a good deal as they used to be...looks like the prices are pretty high. By the time you buy a good Mini, and have the usual work done to it, looks like you are in AR territory. I know the 5.56 quite well, How does the 7.62 stack up as far as accuracy and power compared to the Nato 7.62 (which I also know quite well). I am having trouble justafying 1000 plus for the AR-10 type of rifle. I have found a NIB Mini 30 for a great price, I think I can get it down some more, but are they a good compromise?
