This is a quick video on how to install a Ringsight's articulating bracket on a Cookie Fuel. Note how we use the template for the front screws but clay to locate the rear screw. This bracket is used by skydivers for Concentric and Crosshair ringsights. It is also used for Newton Ringsights.
We thought this video was going to be super quick so filmed it vertically, our apploliges.
