TTI AAP-01 CNC Short Stroke Kit
The TTI AAP-01 CNC Short Stroke Kit includes the parts required to shorten the bolt travel distance and therefore increase the rate of fire of your Action Army AAP-01 GBB pistol.
There are two bolt stroke buffers made from super lightweight aircraft aluminium, so they won’t crack or break into pieces like many 3D printed versions have. One is 4mm thick, the other is 2mm thick. You can adjust the rate of fire by swapping these over, with the thicker of the two increasing ROF the most. The 140% nozzle return spring ensures a snappy and consistent nozzle travel at the increased ROF, making sure that it doesn’t lag behind the increased bolt travel cycles.
