TTI Airsoft Infinity CNC Aluminum One-Piece TDC Hop-Up Chamber for Action Army AAP-01 – Blue

Upgrade your Action Army AAP-01 gas blowback pistol with the TTI Airsoft Infinity CNC Aluminum TDC Hop-Up Chamber. Designed for the AAP-01 GBB pistol series, this one-piece hop-up chamber provides a precision-machined replacement for players looking to refine their pistol’s hop-up setup.

The chamber features a Top Dead Center (TDC) adjustment system, which applies hop-up pressure from above. This design allows players to fine-tune the amount of backspin applied to their BBs when setting up their pistol for a chosen ammunition weight.

Its one-piece CNC aluminum construction provides a rigid housing for the hop-up assembly, while the blue finish adds a distinctive accent to compatible AAP-01 builds. The chamber is intended to improve the stability of the hop-up setup, although actual accuracy and consistency will depend on the complete pistol configuration, BB quality, hop-up components, and adjustment.

Whether you’re upgrading an AAP-01 for regular field use or building a customized gas blowback pistol, the TTI Infinity chamber provides a dedicated TDC hop-up option for the platform.

Compatibility note: Designed for the Action Army AAP-01 GBB pistol series. The supplier does not specify compatibility with every aftermarket barrel, bucking, or modified AAP-01 configuration. Check component fitment during installation and adjust the hop-up before use.
