Review on 🔍 Mitutoyo 050101 Edge Finder Shank: Ensuring Precise and Accurate Machining by Louis Mechtak

I recently installed a scope on a Winchester 9422 rifle. The job required drilling two holes in my beautiful discontinued firearm. The error was zero. With this finder I easily found the right spot, drilled, tapped and mounted the scope. Perfection. Works as advertised. Get it if you want your work to be 0.001 or better.
