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.
