You need to buy a new one or at least one with the 580 or greater serial number (I think that number is right).... this is when they changed the barrel out....about 3 years ago. Any thing before that you will not be happy with. The mini-14 and 30 have a well deserved reputation for being very inaccurate.... Ruger made these rifles with too thin of a barrel for years and as the barrel heated up after just a few rounds the point of impact would string out. From all accounts the newer ones are just as accurate as the standard AR.
