• 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 aluminum, so they won’t crack or break into pieces like 3D printed versions can.

  • 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.
