I don't recall how I came across them, but I found a website for Clark Custom Guns. They tinker around with mini-14s and claim that their fix makes the rifle very accurate. It involves attaching a tube over the barrel, I wish I could remember what it is called, that is supposed to stabilize the whip of the barrel and make it much more accurate. I saw this device featured in a magazine a while back. They do custom work on 10/22's and other firearms and was wondering if anyone has done business with them.
