This video details the process of zeroing a Red Dot Sight (RDS) on a Glock 19 pistol using a ransom rest. The instructor, Russell Fagan, emphasizes the importance of a true mechanical zero, achieved by eliminating shooter-induced errors during the zeroing process. This method ensures the optic is precisely aligned with the firearm's bore, allowing the shooter to identify and correct their own marksmanship deficiencies. The video also covers witness marking for optic security and the benefits of RDS for improved accuracy and situational awareness.
