+1 on the Mini 14. Put a Tech-Sight on it: http://www.tech-sights.com/mini14.htm
You’ll also need a sling. Get a cotton USGI sling here: http://www.appleseedstore.flyingcart.com/?p=detail&pid=10&cat_id=0
Forgot to mention - you’ll need at least two magazines. You’ll be doing mag changes when you shoot the AQT.
When I go to an Appleseed Shoot, I take six mags. You can prep additional magazines during the prep period and be ready to go.
Thanks!
