Upgrade the performance of your factory PS90 magazines with delrin rollers from Dorin Technologies.
Dorin Technologies's PS90 Mag Rollers are made from Delrin, an ultra slick polymer that allows super smooth loading of your PS90 magazines!
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. Their rouch texture allows excessive carbon buildup and over time, won’t slide very well inside the magazine. The Delrin 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.
