Increase your rate of fire and decrease cycle times with the TTI AAP01 CNC Short Stroke Kit.

This kit includes 2 buffers which are installed onto the spring guide to shorten the travel of the bolt giving you faster shots and increased rate of fire in full auto. The buffers included are 2mm and 4mm thick to adjust the increase in ROF. The 140% nozzle return spring helps reduce lag in the firing cycle.
