Level 2 covers all of the same points as the basic upgrade package and more. A high torque motor will be paired with a high-speed gear set to improve the rate of fire, trigger response, and overall efficiency. This replaces all drivetrain and air seal components within the mechbox with aftermarket parts that will be modified appropriately and installed to operate smoothly. Note that the drivetrain will be short stroked and a heavier spring will be necessary to maintain the same FPS output for the high-speed setup.

Trigger response will be improved significantly, and this upgrade service will give you a noticeable performance boost in the rate of fire as well. You should notice an improvement in accuracy, FPS consistency, the gearbox will also be much quieter and smoother.

Estimated ROF:

30 - 35 RPS with 11.1v lipo battery
