I started with a Chinese made bandolier that is intended for SKS users. They have shoulder straps, and are meant to be worn as a chest pack. Since I just wanted to make up a bandolier that can be tossed in a backpack (or whatever), I cut those straps off to get them out of the way. There are a couple smaller straps on the sides, that are intended to be tied around the user's back. I left these in place.
Next, I turned it over, and coated the back side with spray on contact cement. Once this had tacked up, I folded the unit in half, sticking the back to itself using the contact cement. Then I tied the remaining straps together as an additional hold, then again at the very ends, so that they can be used as a handle, or to hang the bandolier from a peg. Each little pouch holds two stripper clips with 10 rounds per clip, so the whole unit holds 180 rounds, or 6 mags worth at 30 rounds each. This seems like a good amount to have enough to replenish magazines, but not add too much weight to a pack. There is a slightly larger pouch, that will just hold a magazine loader, sort of.


The magazine loader is kind of bulky, but it is the only one that I have ever found to work with an AK magazine. It's a known problem with the 7.62x39 AKs; reportedly even the Russians tried and failed to make a magazine stripper clip loader that would work. They remedied that with the 5.45 AKs, which can use a more normal looking "spoon" loader. I added some rubber bands to the closure to help keep it in place. I will find a better one at some point.
If you wanted to, you could probably use a vacuum sealer to waterproof this. Be sure to toss in a desiccant pack or two first, if you do. I wouldn't draw much vacuum, the main thing is to get it sealed.
