Hadron Airsoft Designs Modular TDC Cover allows adjustment of the Mk23 hop-up, externally with a hex key, without loosing the slide movement.
M-TDC is the new design from Hadron Designs, and allows in this form, three possible locations of hop pressure application. By clicking out the adaptor, and rotating 180 degrees, the pressure points can be shifted to provide more detailed tuning.
The M-TDC is a modular design, so, by changing the plates (click out), then clicking in the single screw plate (sold separately), the M-TDC chassis can utilise single screw pressure advantages.
Disclaimer: All aftermarket upgrade parts require necessary skill or modification to install and assemble, please consult with your airsoft technician if needed.
