The newer Mini's have the heavier profile barrel and they group much better. They'll still typically be 2MOA rifles, but honestly what will you be shooting at with a Mini that 2MOA will not do the job? And if we're being honest, most rack grade military AR's are 2-2.5 MOA, and no one ever seems to complain about them.
This notion that everyone will shoot 1MOA in the field just doesn't match reality.
The Mini isn't a military rifle, and you shouldn't think of it as such. It's a civilian sporting rifle that just happens to be the absolute best non-military sporting semi-auto out there, so it can double as a defense rifle in a pinch, and it will do it well. You just can't expect to pump 500 rounds through it in 30 minutes without any issues.
For a general purpose semi-auto rifle, the Mini is just fantastic. The traditional layout means it's slim and thin. The AR's and other military style rifles are really tall height wise, which makes them less convenient to slip behind the seat of a truck and stuff like that.
