The TTI CNC Short Stroke Kit is the go-to ROF upgrade for the AAP-01. By shortening the bolt travel distance, the platform cycles faster — giving you a higher rate of fire on full-auto without sacrificing reliability.
Two shim options (2mm and 4mm) let you tune the travel reduction to your preference. The included 140% nozzle return spring keeps the system running smoothly at the higher cycle rate.
