Modify Quantum Dual Sector Gear

A unique gear set with a simple principle: by splitting the 16 teeth into 2 parts of 8 teeth, we achieve approximately double the existing rate of fire. With the halving of the sector gear teeth, the piston stroke is also halved, meaning the spring will not have the same power, but by using the included spacer, we can utilize the original spring.

It is recommended to use a spring of 120m/s. A weaker spring will not be able to decompress quickly enough, while a stronger one may damage the gears. The tappet plate is shorter because the nozzle retraction time is reduced.

The piston used must have all metal teeth with the following modifications: the 2nd tooth must be completely removed, the 3rd tooth should be halved, and the 4th tooth should be reduced by a quarter.

An inner barrel length (which can be shorter than the external barrel) of up to 200 mm is recommended, along with a cylinder matched specifically to a 200 mm inner barrel.

This gear set comes with a special tappet plate and a spacer for spring compression.
