It's clearly not the same as the current 30 round Lancer mag.

I just don't know if it's an older version as they've changed a few times, but even my oldest Lancers don't look like that.  Does anyone know if that is just some old ones they are clearing out or something thy are trying to pass off as a genuine Lancer?

The ones on the Sportman's Guide site, Are the gen 1 lancers mags.

Just goto gunmagwarehouse for some Lancers

Okay, I think I still have 2 of the gen 1's but they are opaque and I haven't used them in a while so I will dig one out and I think the opaque vs clear made me think it was a different design.  My gen 1's I ordered were also the "off color" I ordered to save a few bucks to try out what was to me then a "new" mag.  I wish they still had the off color ones for sale cause iirc I paid like 8-9 bucks each for them, and they looked just fine to me.
