I really like the Mini. Wish I had bought one rather than the SIG556 I bought. The SIG is utterly reliable, but I just prefer the ergonomics of the standard rifle stock better than those with pistol grips. In the end, I was concerned of accuracy and reliability, and I chose the SIG. It is both accurate and reliable, but I still just don't like it.
I think I may try to trade mine on a Mini 14 here in the near future.
And other than on the internet, I haven't heard of any Mini horror stories, all I've heard from guys I know who shoot them is they are good, reliable, accurate little rifles.
