I had one of the earlier (185 series) years ago and it shot pretty good for what it was intended for but after 4-5 rounds the rounds were all over the place due to the barrel being to thin. My AR wouldn't always strip a new round, last round wouldn't keep the bolt open, misfires, etc. Bought the updated Mini-14 with the upgraded barrel and this is now a whole different ballgame. My AR was made by Stag arms. I have now over 2,500 rounds thru it and not one issue.
