Ordered six recently from Old Western Scrounger.  The mags came in a zipper bag with a light coat of oil.  I tried to fit all of the mags into my various AKM.  And here is the result

WASR10 2014 production – only three mags insert and lock into place.  The other three didn't.

WASR10 2011 production – all six mags insert and lock.

SLR107 – all six mags insert fine

SGL-21 – all six mags insert fine

AMD-65 – all six mags didn't inert.

NPAP – all six mags insert fine

AES10 – all six mags insert but tight

Anyone want pics comparing the Gibbs to other mags?  Range test coming soon.

pics please!

are the 20 rounders available yet?

Last I heard the 20s were supposed to be released this summer but no date yet.
I've heard mixed reviews on the Gibbs mags but they're inexpensive, I'd be curious to see how the Gibbs 20 stacks up to the new Korean 20 round mags. And if the 20s have BHO followers. I'll try a 20 whenever they come out.
