The Rival Arms RA50G101S is designed for the discerning shooter who understands that plastic guide rods can often chip, crack, or break. This not only leads to feeding or ejection failures, but flex can also impair accuracy. We have developed our Guide Rod Assemblies to overcome these common problems, ensuring a lifetime of consistent and reliable performance.The guide rod we provide is made from a premium spring (stock weight) and comes fully assembled. We use a CNC machine to sculpt it from a solid stainless steel billet, ensuring a part that is robust and highly resistant to corrosion. Best of all, no expertise is needed for installation - no gunsmith required.
