Is your AAP-01 not fast enough? The CowCow Aluminium Buffer for AAP-01 is designed to satisfy even the most ravenous appetite for speed! This set includes two recoil rod spacers which are CNC machined from 6061 aluminium to provide a great balance between strength, precision and low weight. Adding one or two of the spacers to your guide rod will reduce the length of travel of the AAP-01 bolt and speed up the already impressive cyclic rate of the AAP-01 in both semi-auto and fully automatic fire.

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.
