Rock Your Glock stainless steel guide rods provide a decisive advantage for all Glock owners. Special features include a rigid stainless-steel body that improves lock up by completely removing "guide rod flex". The hex screw removable tip allows the user to choose various spring weights that will calibrate the ammunition to their Glock. Utilizing the G4 Adapter Ring with the RYG G3 Guide Rod Assembly shooters can replace their OEM polymer guide rods for a quality stainless steel upgrade with the spring weight of their choosing.

The NDZ Generation 4 Adapter Ring installs under the retention end screw thereby making up the difference of space in the front of a generation 4 slide as well as retaining the spring accordingly.

ISMI premium springs are manufactured exclusively with certified aerospace specification alloys; stainless or chrome silicon. Then the springs are heat treated, shot-peened and stress relieved after winding to enhance performance and durability.

Please Make sure you are using the correct loads for the springs or you will have cycling issues.
