This is a 13:1 gear set made by GMT, 13:1 is one of the fastest gear sets you can buy. Stock gear sets are around 18:1. For some reason many manufacturers don't actually label the ratio, but rather use code names. Most manufacturers "high speed" gear sets are 16:1, so this set is much faster than that.
A note about airsoft gears: Upgrading gear sets is done for two reasons. The first is that after market gear sets are much stronger and better made than stock gear sets. The second is to provide higher rate of fire or higher velocity. The key factor that allows a gear set to do these things is that it allows the motor to operate closer to it's peak power. The peak power that a DC motor provides is at 50% no load speed and 50% max torque (it's a linear relationship). For instance if you run a stock motor and stock 18:1 gears with a strong spring like a m130 the rate of fire will be very low. This is because the motor has to provide a lot of torque which puts it below it's max power output speed and torque level. If you were to install a gear set with a higher ratio the motor won't have to provide as much torque and will be closer to it's max power, which increases your rate of fire. This applies the same way for increased rate of fire, weak spring and stock gears will put a stock motor to far above it's peak power. Because of this relationship gear set ratios should only be changed in conjunction with a spring and/or motor change and are often only necessary for large changes in those. Installing a high speed gear set in an otherwise stock gun might only increase your rate of fire slightly or even decrease it depending on the stock spring and motor combination.
Please ensure that the screws securing the sector gear together are correctly tightened (loctite wouldn't be bad idea either) as a few sets they weren't tightened fully.
