I called a few different NATO numbers a while back and inquired about that document.  All the people I talked to told me that it was not just “available” to anyone that simply wanted it.  I found that answer odd though considering every other NATO document under the sun, is readily available on the internet.

My question is:
if there is no STANAG 4179, where does a person get the standardized magazine measurements from? The few dozen companies that make magazines can’t have just busted out their calipers and measured an old COLT magazine they had lying around, and called it day.

Or could they have?

The original Magpul P-Mags never fit properly in “some” AR-15 lowers.  To me, this means that they didn’t use the standardized model of an AR-15 magazine to create their polymer one.

If anyone has the STANAG 4179 document (if it exists :)) please contact me, I’d love to see it.   Otherwise I’d like to see any document that has the AR-15 magazine measurements in it, so please send it over!
