About the Docter/Noblex mounting standard
The Docter/Noblex standard, a pioneering design in the field of open reflex red dot sights, is characterized by its four sockets, one in each corner, and two screw holes. Each socket measures 3 mm in diameter. Over time, numerous red dot sight manufacturers have adopted this design, primarily due to the abundance of aftermarket mounting solutions available and its reputation for simplicity and reliability. Its uncomplicated design has established a benchmark for mounting standards within the industry. It is found almost exclusively on open reflex red dot sights.
