This is a high-end gear set for electric guns made by Siegetek Concepts in the USA.
The sector gear is single, and the gear ratio is 20.8:1.
This gear is exclusively for Ver.2 Long (19-tooth piston).
The material is nickel-chromium-molybdenum steel, machined and used in high-stress parts such as aircraft engines.
The surface is HRC55+ due to carburizing and quenching, making it incredibly tough, unrivaled by other electric gun gears.
The cut-off latch of the sector gear has a special shape,
which reduces the occurrence of trigger lock, preventing semi-automatic firing.
Similar to next-generation electric guns, the small teeth of the bevel gear also serve as the teeth for the anti-reversal latch,
so a next-generation anti-reversal latch is required.
You may find blackish rust on the nitrided silver surface of the gear,
but this is not on the gear itself. It is corroded chromium oxide adhered to the surface,
so it does not affect performance and can be used as is.
Please use a spring load of 15kgf or less as a guideline for the load during piston release.
Always be careful not to exceed the muzzle energy stipulated by the Swords and Firearms Control Law.
