I had a Mini 14 for awhile. A barrelled action of one was left on a shelf of a house that I bought in 1986. I sent it to Ruger to be reblued and while it was there had them to check it for accuracy. Even back then I heard stories of their inaccuracy. When it returned I put it in a stock that I had bought at a gun show and took it to the range. It shot pretty well -- until the barrel heated up. Once the barrel heated up its groups opened up significantly. I think that a lot of the complaints about their inaccuracy stem from shooting them with a hot barrel. It didn't take much to heat it up either. My vote for the most dissappointing gun would be the Remington 742 that I once traded for. I never could get that rifle to shoot well. I carried it around to more than a few gun shows before I finally traded it off.
