From SHS we have a 16:1 Complete Gearset.
This gearset is a suitable replacement for Standard (18:1) Gears found in Version2, 3 and 6 Gearboxes. This SHS Gearset offers an Upgrade to the Standard (18:1) Gears most commonly found in AEGs as the slightly lower ratio will decrease the cycle time of the gearbox gaining an increased rate of fire without loosing much torque or causing any siginificant increase in strain on the original motor.
Features:
Chrome molybdenum alloy steel made sector gear — High strength, not easy to deform
CNC machining, enhanced gear to be more durable and bearing stronger spring
New axis design, improve gear concentricity
Integration of axis & gear instead of cooper shaft guide, more durable
Lower electricity consumption & lower noise
