For a firearm to be effective, it needs to be reliable, durable, consistent and accurate. When finished parts have burrs or other defects, the detrimental impact it has on the gun is severe. With Swiss machining, you avoid these issues and provide a product that can be trusted when needed most.

Fixed head turning machines of the day were not capable of holding the tight tolerances required for these small diameter parts. So the Swiss watchmaking industry developed a different kind of turning machine.
