Improve the performance of your factory PS90 magazines with Man Kave's delrin rollers from FNspecialties.com.

Man Kave's PS90 Mag Rollers are made from Delrin plastic, a smooth material that allows your PS90 magazine to function flawlessly!

PS90 Mag Rollers can be installed in minutes and are one of the least expensive upgrades you can buy. The factory mag rollers are injection molded, so they are rough and don’t slide very well inside the magazine. The PS90 Mag Rollers improve on this tremendously.

You start to notice the PS90 Mag Rollers when you load the first round or when your loading the last few rounds. Once you install the Delrin rollers, loading the mags are as smooth as they can be.
