TDC (Top Down Conversion) Hop Up Modification

Hadron gained popularity due to the success of the MK23 TDC system with interchangable pressure plates that have either a single screw, twin screw and now the triple screw to choose from. The TDC mod is easy to install and can hugely enhance the performance of your MK23 pistol. Paired with the H-Plate, this is the ultimate combination for any user.
