Binoculars and riflescopes are made up of as few as 80 parts and as many as 150 parts, and require machining precision down to the micron level.
Furthermore, riflescopes are subjected to extremely large shocks when fired, so in addition to high-precision machining of parts, advanced assembly techniques are essential to ensure smooth and robust movement.
