Bore-up is the name for parts that have an extended shape to accommodate as much air as possible. In layman's terms: more air in the cylinder means more pressure in the barrel and thus increased performance of the weapon. Primary are these parts designed for weapons with a longer barrel, or when replacing the basic barrel with a longer one (for example, by extending the inner barrel up to the silencer).
However, bore - up sets need sufficient force to achieve the required power, so it is generally recommended to use M130 and higher springs.- Compatibility with other sets: NBU Guarder, NBU Systema
- Compatibility with gearboxes: Gearboxes according to the Tokyo Marui standard
- Tried: Classic Army, SHS, Super shooter, Retro Arms, CYMA
Recommendation: The rollers are delivered from the manufacturer slightly dusty on the inside. Prior to installation, we recommend cleaning all parts with silicone spray, polishing with a cloth or paper towel, and then lubricating with silicone or Teflon paste for proper operation.
