Awesome tutorial--- makes sense that the 25-/30-round magazines are Modelo A magazines--- I have heard on numerous occasions that the 30-round magazines only hold 26-27 rounds of 7,62 NATO!!! :biggrin:I would like to share some info regarding the so called 'large capacity' 7.62x51 CETME mags.
I got a couple of CETME magazines sold as 30 rounders. It did surprise me that the 30 rounders were taking only 26 rounds each but never gave it a second thought.
Then I found what the seller was calling a 25 round magazine, which was slighter shorter that the so called 30 rounder but definitely larger than the standard 20 rounders. When I loaded that 25 rounder I only could get 20 rounds on it!!!
So I went to my reference books and started to look for info on those 'large capacity' magazines.
It seems that those mags were originally made for the CETME Model A-2 in 7.62x51 CETME-NATO (basically a underpowered 7.62 NATO round) and were actually meant to be a 20 rds and the larger a 25 rds capacity mags.
Cetmes A-2 in 7.62x51 with 25 and 20 rds mags.
Both magazines fit and function perfectly on the later Models B and C CETMEs.
So, is there or ever was a real CETME 30 round magazine?
The answer is YES. The Model A-1 in 7.92x40 and 7.62x40 had a banana shaped 30 rounder:
Here the picture of the whole 7.62x51 collection: A-2 25 rounder, A-2 20 rounder, B&C 20 rounder and 5 rounder.
