What is the NBU? This is shortcut of New Bore-Up. Parts (usually piston and cylinder head, cylinder and nozzle) have an enlarged internal diameter and can accommodate a larger volume of air. In order to achieve the appropriate effect, it is recommended to use the spring M130 and stringer

Please apply silicone oil on the cylinder head before nozzle put on.
Place the nozzle sensitively on the head to avoid damaging the thin rubber rings

Note: Different manufacturers may use different nozzle lengths for the same weapon model. Please make sure that nozzle length meet your needs. A poorly chosen nozzle fundamentally affects the performance, or gunfire-ability. Under ideal conditions, the nozzle should fully fit on the HopUp rubber band and not touch the chamber surface.
