Why are ak magazines curved?
« on: August 14, 2009, 02:43:40 PM »
My little girl saw one of my AK magazines and asked why they are curved and not strait like the AR mags.  I had never really thought about it before.  Of course I made up some story about the bigger bullets and it would be too long if it was  strait and the spring needed an angle to push them up.   :lol: 

I am sure there is a very easy explanation to why they are curved.  Does anyone know?

 It makes them slightly more compact, so you can have a slightly lower profile shooting from cover. I am sure there is also some mechanical benefit to it as well.

  FWIW, AR 30 round mags also have a bit of curve to them, it's just not as pronounced....

Its not a compactness thing, its a geometry thing. They have to because of the taper of the case..

Look at a .223 compared to a X39 case, the .223 case is more or less straight, the x39 has a visible taper.

Think about it from a geometry perspective...

The reason, aids in extraction.. All the extractor has to do is move the case the slightest bit and the entire case is clear of the chamber.. A straightwalled case has to slide the entire thing out before its clear...

In a fouled gun, it can make the difference between going bang and not going bang...

I also believe it has to do with the feeding issue as well.....  GL

Thanks guys.  My kids are always asking me questions that make me think.

I tried to tell her it was because it looked cool but she wasn't buying that.   :lol:

I believe it's because the rounds are bent to allow them to shoot around corners.

OK, sorry.  Couldn't resist.  TheSpork is correct.  The mags are curved, and must be, because the 7.62x39 round is tapered.  The taper eases feeding and extraction.

Ah yes, a picture is worth a thousand words to an 8 year old.  That gave me an idea so we just laid out 10 7.62 x 39 rounds  and 10 .223 rounds.  That made it very easy to see why the AK mag is curved.

If you notice, the AK-74 mags aren't as curved.
