An upgraded hammer is a great foundation to any upgraded AAP-01 build, especially if you are an HPA user!

Full description


The CowCow SS Hammer for AAP-01 replaces your original hammer body with a strengthened body, but will require small parts such as springs and rollers to be transferred over to the new hammer body. The Hammer is CNC machined for additional precision and is strengthened in order to prevent warping and structural damage from repeated, hard use. MAF polishing technology is applied to the exterior surfaces of the hammer in order to reduce friction and wear on other parts, and improve the efficiency of the pistol with a more precise fit and smoother operation. If you want to push your AAP-01 to its limits, at some point you will need this!

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.
