Ruger factory magazines and OE magazines are from two different companies and are not affiliated with each other.
OE ( Original Equipment ) magazines might work just fine . but if you ask me I believe they are being a little deceitful with the name and that is why they call themselves that.
Not necessarily true.
Eric Schellhorn, Director of Sportswear & Accessories, Ruger® Firearms; "Ruger's Mr. Magazines" called me on April 30th as the result of a suggestion I sent to Ruger's CEO. I told the CEO of my review of OE's 20rd straight mags vs my Ruger brand 20rd mags and how I thought the quality of the OE mags was better than Ruger's current ones.
Eric wanted to discuss my review and findings and he stated that they buy mags from different suppliers; they don't make them themselves. When I asked if they ever bought them from OE he changed the subject and never answered. As some early Ruger Mini-14s apparently came with straight 20rd mags (per posters on PerfectUnion.com who claim to have got them) it's possible that OE did in fact supply Ruger with mags at one time.
