What is NBU

It is an abbreviation of New Bore-Up. The parts (usually a set of piston head, cylinder head, cylinder and nozzle) have an enlarged inner diameter, so they can hold a larger volume of air and achieve higher performance. To achieve the proper effect, it is recommended to use M130 to M170 spring. The increase in performance due to NBU is about 3 - 10 m/s.
