This .200″ diameter guide rod and spring can be used with your stock OEM recoil spring to create a dual-spring assembly which adds an additional 8 pounds to the factory spring load.
It can also be used in conjunction with any of the Wolff recoil springs as well. Counter-wound coils prevent spring nesting with the factory spring.
A slide bushing is also included and required to prevent the inner spring from sliding through the hole in the front of the slide.
For Witness Hunter model only.
