http://www.greatwestgunsmithing.com/mini14.htm they do quite a bit of Mini-14 work and get rave reviews from people who have had work done. Bed the action and have the trigger work done and you should see groups shrink add a strut to minimize barrel whip and you should have a great shooter. Enjoy the rifle they are a lot of fun but you can go through ammo pretty quick with one.
