Tridos TDC Upgrade Kit for AAP-01

→ Thumbscrew + Set screw
→ Fine pitch threads
→ CNC nub plate
→ Comes with drill jig

⚠ Compatible only with stock hop-up chamber
⚠ Included drill jig works only with the original AAP-01 / AAP-01C upper
⚠ Thumbscrew might now work with aftermarket uppers

This TDC kit for AAP01 replaces the stock hop-up adjustment mechanism with a screw that pushes down on a custom CNC nub plate.

Compared to other TDC's on the market, our version uses fine-pitch threads compared to standard M4 threads, which leads to 28% increase in resolution. You can make insanely precise adjustments this way and tune your shooting trajectory to perfection. 

Kit comes with set screw and a thumbscrew so you can choose whichever you like best. The included thumbscrew is compatible with our Top Rail with built-in Clicker.

→ Using an aftermarket upper? You will need to purchase Universal Drill Jig kit to drill the hole in the right place. 

✖ Not compatible with AiRReX Custom-A CNC Upper for AAP-01
