Low Noise High Speed Gear Set
SHS 13:1 gearset+ High-speed: RoF is 40 shots per second or more
SHS 13:1 gearset+ High-torque: RoF is 30 shots per second or more
All these data come from spring M110,M120's test.
SHS 13:1 gearset Can be used at Version.2 and Version.3 gearboxes.
Inner barrel requirements: It is suggested to use 6.03,6.04,6.05 barrel
because of the fast RF. The 6.01,6.02 barrel are not applicable. In addition,
the length of the inner barrel must be less than 400 mm because it is very easy
to jams BBS and slip piston or gears if the inner barrel is too long and too narrow.
Piston requirments: SHS full steel 15 teeth piston is the best choice
Spring requirements: It is better to use the slingshot M90,M100,M110,M120,M130.
The M140 is also applicable but with a greater wear down of the gear and piston.
Gear box Requirements: It is strongly suggested to use the 9 mm bearing. It is also
recommend to use a spring guide with bearing and a piston head with bearing
