This stainless steel guide rod is a direct drop-in replacement for the factory recoil spring guide rod in the FN 502 pistol. Its primary function is to add mass at the muzzle end, increasing the total guide rod weight from 2.3g to 22.4g. This additional mass helps reduce muzzle rise and improves sight return speed between shots, providing a more consistent platform for follow-up shots. The rod is machined from stainless bar stock, then heat treated and polished for corrosion resistance and smooth cycling.

FAQ
Is this a captive or non-captive guide rod?
Non-captive. The recoil spring sits freely on the rod and must be aligned during reassembly. Take care when removing the slide to prevent the spring from ejecting.
Does this require any permanent modification to my FN 502?
No. It is a direct drop-in replacement. No fitting, filing, or permanent changes are needed. You can return to the factory guide rod at any time.
What maintenance does this guide rod need?
Apply one drop of light gun oil to the rod at install and during regular cleaning cycles. Wipe clean and re-oil if the rod shows signs of carbon buildup or dry cycling.
