Angel Custom KRATOS II AEG Piston

The pre-adjusted angle of engagement (AOE) is designed to ensure the sector gear teeth meet the piston rack at the optimal point. This reduces unnecessary stress on the piston and gear teeth, which helps prevent premature stripping and improves the overall longevity of your gearbox.

The KRATOS II is designed for broad compatibility with most standard Airsoft AEGs. However, because internal tolerances vary between brands, you should always check for smooth movement in your specific gearbox shell before finalizing your build.

The Gold Titanium Nitride coating provides a low-friction surface that helps the piston rack glide smoothly against the sector gear. This coating also increases surface hardness, which is critical for maintaining durability in high-cycle or high-power setups.

Yes, this piston is specifically engineered to handle the stress associated with high-torque gear ratios like 32:1 and 40:1. Its reinforced DuPont Super Nylon body and hardened steel rack are built to withstand the increased load these configurations place on internal components.

The 13.5 tooth count is a specific design choice that helps prevent 'piston pickup' issues, where the sector gear engages the piston too early during the cycle. This configuration is particularly useful for high-speed builds where timing is critical to prevent gearbox jams.
