  • For Action Army AAP-01 Assassin GBB Pistol

If you want your AAP-01 GBB to be running at its absolute best an enhanced nozzle would be a great choice to get the most out of this impressive platform. The CowCow Enhanced Plastic Nozzle Set includes an enhanced nozzle, nozzle valve, valve lock pin, valve spring and enhanced piston head, and when installed these parts should improve the shot to shot consistency, provide smoother cycling performance and improve the rate of fire of the AAP-01 Airsoft GBB.

Full description


The CowCow Enhanced Plastic Nozzle Set is designed to replace the original nozzle, nozzle valve, valve spring and piston head with enhanced parts for improved air seal, which will lead to improvements in all aspects of the AAP-01's performance. The nozzle is the heart of any GBB pistol, and having a high-quality nozzle set is essential for a properly upgraded GBB pistol.

The set includes an enhanced nozzle and nozzle valve constructed from injection moulded polymer, an oil-resistant rubber enhanced piston head and a spring steel valve spring, with a stainless steel valve lock pin. These parts are all precisely made and are intended to provide a performance leap for the already impressive AAP-01 and make it more than suitable for use as a primary pistol, or as a primary installed into a carbine kit.

If you are building your dream AAP-01 GBB pistol, this set should definitely be on your parts list. Whilst the individual components of this set are available separately, CowCow has put them together for convenience, and for added value!

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.

If you require help with fitting any parts feel free to get in touch with us via our Contact Us Page.
