Dorin PS90 Delrin Magazine Rollers

The Dorin Delrin mag rollers replace the factory PS90 / P90 magazine rollers with low-friction Delrin polymer parts. The factory rollers are functional but accumulate carbon over time, which increases drag inside the magazine and contributes to follower wear. The Delrin replacements glide more smoothly, slow carbon buildup, and extend the usable life of factory FN magazines.

At $7 a set, this is the cheapest reliability upgrade in the entire PS90 catalog. PS90 owners who run their mags hard or who have older mags showing wear should plan on replacing rollers as routine maintenance. Drop-in install with no tools beyond standard mag disassembly.
