TDC Upgrade Kit for AAP-01

⚠ Compatible only with stock hop-up chamber
⚠ Included drill jig works only with original AAP-01 / AAP-01C upper

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 thumbscrew so you can choose whichever you like best. 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
