DPM CZ TS2 Mechanical Recoil Reduction System w/ Spring Plug 5.1in/130mm Barrel 12 Combinations Orange Bull Barrel. The factory spring plug-bushing (not included) must stay installed and co-operate with the DPM Recoil Rod (108mm/4.25" long). This system works due to the multi-spring intricate rod (3 springs) and controls the functionality of the gun. The third spring which is contained within the rod controls the movement of the slide so it never rams on the frame.
