There are good ones and bad ones...I have 2...one shoots MOA or better, the other...well, not so good. That being said, I also have 2 AR's (a Bushmaster and a Rock River)...the Bushmaster shoots no better than the worse of the two Mini's, and the Bushmaster has a Pac-Nor barrel and upgraded trigger. On the other hand, the Rock River shoots sub-MOA all day long. Bottom line...you can have good and bad Mini's and AR's. I prefer the feel and look of my Mini's over the AR's...but that Rock River AR is a very nice weapon, but it ran me close to $1400.
