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. 

Required for installation:

  • drill or drill-press

    Great improvement of AAP-01

    At a fraction of price of after market hopup chamber I've got very high quality product, quick and easy installation and no more of opening upper receiver, scratching hopup wheel with a thumb, closing receiver and test if that did help. After few hundred shots it keeps hop exactly where it was set.
