Gen 6 Glock 17: Because These Aren't Plates
This video explains the function of the optic mounting system on a Gen 6 Glock 17, specifically detailing how the gasket/washer component acts more like a crush washer than a plate. It highlights how the rear of the component is thinner than the front, causing it to sit slightly higher than the optic cut. This lift provides a small amount of torque to the front of the optic, preventing forward and backward movement by increasing the shear resistance on the optic's mounting screws.
