Small world, I started with a blue 580 series I bought in June '08. The ATI stock had just come out. I shortened my barrel to 16'', threaded it 1/2''X28'' and installed a Phantom flash suppressor. My barrel schroud I made from an aluminum walking cane. A propoint red/green dot from WallyWorld works great on the Mini. You will like your setup- this stock is fun to shoot with. Congrats on your B'day setup!
