Jed, RR hit the mini pretty accurtely...I might add to that.

Accurizing the mini is done by several gunshops and a friend had one rebarreled to .17 Remington. It had fine MOA accuracy but still threw the brass all over the country....of course we knew this was going to happen because it's a semi auto. If you choose to have your mini rebarreled and accurized ( a trigger job is manditory in my opinion) consider the .17 Rem, the .20 Tactical, or the 6X45 as well as the .223

I believe you'll be happy with your accurized mini. Of those that have gone that route all that I know have been very satisfied.
