The Rival Arms Tungsten Stainless Steel Guide Rod Assembly for the Glock 42 (brand part number RA50G401T) replaces the factory plastic guide rod with a CNC-machined, solid stainless steel billet rod built to resist the chipping, cracking, and flex that can cause feeding or ejection failures over time. Rival Arms ships the assembly fully built with a premium spring at factory stock weight, so there’s no need to source or fit a separate spring, and no gunsmith is required for installation. Because a stiffer, truer guide rod flexes less than a factory plastic rod, it also helps address the accuracy inconsistencies that rod flex can introduce. It’s a straightforward, durable upgrade for Glock 42 owners who want factory-spec function with a more corrosion-resistant, longer-lasting part.
