Tridos TDC Upgrade Kit for AAP-01

£22.00
Tax included Shipping calculated at checkout.

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.
