Double Sector Gear with Tappet Plate V2

This attractive set of piston wheel and tappet plate will increase the cadence of the gun, but at the same time, due to the half-gear, it will also reduce the power, so it is necessary to use stronger springs. 

DSG stands for double half-geared, where twice the round will be fired per cycle because the piston is only extended halfway. This will greatly increase cadence, but as written above, it will reduce power, so it is ideal to use it with a spring of at least M140 and above.
