Question on AR15 magazines

[Miky]

Hi all,

I've done a few internet searches and can't find any answers so I figured I would try here. At the rang I frequent, I have seen a good number of USGI AR15 magazines, most with green followers. Some of these green followers are marked with a black "S". Does anyone know what this marking indicates?

On brand-new magazines? Any info to support your answer?

Its been my experience that manufacturers dont go through extra effort to identify deffective parts.

Is this a guess or a real answer?

It's a manufacturer's mark.

Possibly Sanchez green followers?

The Green Followers (GFs) were first seen in Sanchez magazines in 1988, and became standard issue for all M16 magazines in 1992. Sanchez mags should be considered on par with any USGI-spec mag. Made from early 1980s-early 1990s.

Floorplates stamped:

(DSI) SANCHEZ ENT.

Was the "S" drawn on , like with a sharpie? Or did it look like it was factory?
The only things that come to mind are either "Service" (as in the mag had been serviced, or needed service) or "Simunitions". Odd place to mark a mag if it is a mark.

Just for info: Sanchez mags with the black followers should be avoided or fitted with a green USGI or a quality aftermarket follower.
