A bore up nozzle designed to push a large volume of air behind each BB. This can dramatically improve the accuracy of your shots providing the rest of your Airsoft gun is set up correctly.

Full description


You must combine this part with a bore up cylinder, cylinder head and piston head for your gearbox to function properly. Using a bore up kit usually allows you to use a shorter or weaker spring too. This can result in a quieter sounding rifle upon being fired. Inside you have an o-ring to improve the air seal of your gearbox for improved shot consistency.


  • 22.40mm long replacement/upgrade air nozzle
  • Larger than standard inner diameter to release a large volume of air
  • O-ring internal edge to hugely improve air seal comparted to most standard out of factory builds
  • A must have component for anyone looking to make their rifle as efficient as possible
  • When installed correctly with other components this could reduce the noise your AEG rifle outputs
  • Can improve feeding of your ammo
  • Offers consistent performance 
  • Useful spare part to own
  • Intended to replace damaged or worn out air nozzles

Package Includes:

  •  Bore Up Air Nozzle SIG

Special Instructions:

Usually with bore up components, you must have a complete bore up set including piston head, cylinder and cylinder head. Please ensure you have these parts before installing this air nozzle.

Parts Fitting

Upgrades and Downgrades should only be undertaken by experienced players, or Airsoft Technicians. Please note, changing any internal parts of a weapon voids its warranty unless done in-house by our staff. 

Please ensure that when fitting parts the part purchased is the correct part, as once a part has been fitted we cannot accept return.

We do know that players love to tinker, so we're here to give you help should you require it, and if needed you can get in touch with our workshop for more help!

Unique Parts

Please note that some parts may be unique to a specific brand of weapon. For example: Parts for an ASG M4A1 may not fit an ICS M4A1.

Parts from the same brand typically have a high chance of fitting, though be warned, some replicas use unique parts, so please ensure the part will fit before you attempt to fit it.
