The Rival Arms Stainless Steel Guide Rod Assembly for the Glock 43, 43X, and 48 (brand part number RA-RA50G301S) replaces the factory polymer guide rod with a CNC-machined stainless steel billet rod for added strength and corrosion resistance. Rival Arms ships this assembly fully built with a premium spring at factory stock weight, so it drops straight into the pistol without sourcing or assembling separate spring and rod components. Because it’s a direct-fit factory replacement, no gunsmith fitting is required, and Rival Arms backs it with a limited lifetime warranty. It’s a straightforward upgrade for Glock 43/43X/48 owners who want a more durable guide rod without changing their pistol’s recoil characteristics.
