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", replacing the OEM polymer rods. The hex screw removable tip allows the user to choose various spring weights that will calibrate the ammunition to their Glock.

Please Note: If looking to use in a GEN 4 configuration you must purchase a RYG Adapter Ring in addition to this guide rod.

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.
