The link to the Polish mags didn't work out, but your 2nd link did. I think I might go for this combo pack, let me know what you think before I go to town.
It looks good to me. The Polish mags are synthetic black plastic/polymer, so lighter and weather resistant. I mostly have East German and Chinese AK mags myself, but the deal on the 4-pack and pouch is sweet enough I think I'll go for it as well. Try here for the $10 Polish magazines again.
Also, I'm looking for a good 3-point sling for my AK. Anything stick out in your mind as a good brand/buy? I see them here for $15 and there is another model here that is $22.99.
I go for something a little different with the heavier AK47s and RPKs, first of all preferring as wide a sling as possible to spread the weight, and not one made of nylon, should it come in contact wiuth a hot barrel. Then if I'm feeling antsy, I'll pop in a 75-round Chinese RPK drum, which comes in a pouch with its own over shouvder sling. I relocate the buttstock swivel on my AKs to the top of the buttstock near the buttplate and let it hang waist-high. The strap/sling for the drum pouch goes over the other shoulder, and since it carries the weight of the drum and ammo, reduces the load on the other shoulder considerably.
The only 3-point sling I've worked with extensively is the Giles sling, which I use with some bolt rifles, folding stock AKs, and my 8-cell aircraft landing light flashlight. Details here, available from GG&G *here, or
