From the articles on the website, its been around for a while. The guys at M14 public forum are talking about it, some having just acquired the mount. Its sounds really good. The hard stainless steel dowel that is imbedded into the mount self centres in the v groove in the receiver, so that it repeatedly zero's to the same location. Guys are saying it retains accuracy after removal and reinstall. Sounds pretty good for an under $100 scope mount. Sounds like a good option for someone wanting his rifle to be convertible between scope and iron sights. I'd like to hear more about how well it holds zero.
