I've had four Minis, and am now on my fifth AR. They've all worked as I wanted, with no problems from either.
For hunting, I prefer the ergonomics of the Mini. It's certainly as reliably accurate as any AR for the first shot on a coyote. It's just not a benchrest paper puncher. So?
The AR can be set up as a tack-driving target rifle, and is a better "social gun". However, the Minis will certainly hold minute of torso all day long.
