This TDC hop-up unit by TTI Airsoft is designed for the KJ Works Shadow 2 CZ75 GBB Airsoft pistol series. CNC machined using high-quality aluminum alloy, it is very lightweight and durable. This hop-up unit features the TDC (Top Dead Center) adjustment system allowing for a more consistent shot-to-shot accuracy and less projectile deviation as it applies even pressure at the nub and center of the Hop-up rubber. It is a simple drop-in installation and does not require modification to fit.
This particular TDC is compatible with only KJ Works Shadow 2 / TS2 with the Tilting Outer Barrels, as KJ has updated the design of their CZ Shadow 2 / TS2 pistols with a Non-Tilting, Fixed Outer Barrel as of May 2026.
