The main feature of the TDC is that the nub is centered in the TDC base as shown in the picture.
Thanks to the design, there is no movement of the nub and it presses evenly on all sides with just one screw.
Another important feature is the way the nub is constructed.
The current design utilizes the full potential of the bucking patch.
Thanks to these features, the overall performance of your MK23 will be improved.
The next big feature is the ability to use this TDC set with both barred and non-barred barrels, utilizing the full potential of the mating contact surface by simply rotating the nub (as in the pictures).
