I don't think there is anything inherent in the Ruger design that results in the Mini-14 not being especially accurate. I think Ruger just never spent the time and money needed to tune those rifles, plus there has been little demand for improved barrels, better bedding and the whole accuracy tuning game. Basically, the gun has been treated as a medium power plinker, not a rifle worthy of a place on the target ranges. Of course if the money were spent to "accurize" the Mini-14, it would no longer be inexpensive.
The AR-15, on the other hand, has had millions of (mainly) government dollars poured into making it an accurate rifle even though the first ones were not especially accurate.
