Description
CowCow's Stainless Steel Hammer Housing is an essential upgrade if you are hardening up your AAP-01 for a lifetime of high-stress use with an HPA adapter or upgraded steel components. While it works great as it comes, the AAP-01 is known to have weaknesses in its hammer group which will rear its head with heavy use, especially when used with short stroke kits, HPA adapters and other speed enhancements.
This hammer housing is CNC machined from stainless steel and is flawless in form, guaranteeing reliable engagement and easy installation. Being constructed from Stainless steel not only adds strength, but also reduces friction resulting in better overall efficiency from the platform as well as reducing parts wear.
If you have an upgraded AAP-01 and you have not yet replaced your hammer housing it's a good idea to get ahead of potential failures by installing the CowCow stainless steel housing. This means you can avoid the sudden disappointment of your pistol failing mid-game, and prevent any upgraded steel mechanical components you have installed from wearing out the original alloy parts.

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.
