Scope-Ring Alignment Tool for Hunting Rifles

Jerry Schmidt, an avid shooter and hunter from Montana, has created a tool designed to help install single-dovetail or double-dovetail rings on hunting rifles. Jerry’s invention, the Scope-Tru Alignment Bar (patent pending), is unique. Unlike most other alignment systems, this is a single, long precision machined rod with a pointed forward end. You work on one ring at a time, first setting the front ring in the dovetail and then setting the rear ring. The process is shown by Jerry in the video below.

Jerry explains: “The Scope-Tru Alignment Bar is a tool designed to install both standard ring/mount systems, and dual dovetail ring/mount systems. The tool provides significant leverage to turn the dovetail rings into their bases. By observing the pointer on the end of the bar, it is easy to align the ring with the center of the barrel, thereby assuring that the ring is installed at 90 degrees to the axis of the bore. Because the bar is a one-piece tool, it is possible to get the rings into nearly perfect alignment with each other, and near perfect alignment with the bore axis.”

The photos above show how the tool is used to install and align a set of standard hunting rings (with rear windage adjustment). You start with the front ring, rotating it 90 degrees in the dovetail, and then align with the center of the barrel. Next, slide the tool rearwards and loosely set the rear ring in place. With both rings adjusted correctly, the alignment tool will be perfectly centered and both rings with be subsequently squared at 90° to the bore axis. Schmidt says he can install conventional rings with this tool, tighten them to spec on a rifle scope, and there will be virtually no marks on the scope tube. (Of course this would require that the rings are extremely well made with no burrs or highspots on the trailing and leading edges.)

The Scope-Tru Alignment Bar is CNC-machined from TGP bar stock, and will be offered in both 1 inch, and 30mm diameters. The durable bar is designed for regular, long-term use by the professional gunsmith, the home gunsmith or “gun crank”, and retail or wholesale sporting goods store staff. The 1″-diameter, all-steel Scope-Tru is can be purchased for $135.00 plus shipping and handling. The version for 30mm rings AND a new combo 1″/30mm Scope-Tru tool are both in final development, and could be available in the near future.
