I think I,ve decided to buy another mini 14, the last one I had was back in the 80's, an A- Team style folding stock stainless. I really like the look of the new "tacticool" mainly the idea of weather resistance. I'm going to try and get used and understand 580 series is supposed to be more accurate. Are all the newer barrels the same? I read on another forum that even among the 580 series that there have been some barrel changes. If I happen upon a ranch wood stock is it going to be the same as a synthetic as far as sights, mounts barrel etc.? If I buy new probably getting it at Bi-mart. Any thoughts that chain store guns are inferior? Would really appreciate any feedback on owners of 580 series! Thanks!
