I've got a 7 pocket Chinese that 6 pockets are for 20 round AK mags and the 7th is for the cleaning supplies, etc. All are the same size and too short for 30rnd mags, but the 7th is lined to protect from oil/solvent. This is different than the other Chinese 7 pocket bandolier I've seen. The other one has 5 pouches for 20/30rnd mags and the outer 2 are smaller which may be for stripper clips or something???
Might try and find another one because I fit my daughter's 20rnd Tapco mags and they fit great.
Don't have mags yet but they are on the way.
