I must tell all of you that I have purchased 2 chest rigs from these folks, one for AK which I use for my Mini-30 mags, and one for my duckbill SKS mags. These are both extremely high quality units and I believe if I never live through a shtf or worl type situation these mag holders should last beyond my life expectancy. I also have the belt mag pouches made for the SKS Tapco 20rnd mags, this product is of the exact same quality as the chest rigs and should also last one many, many years of even hard use.
The only thing I have purchased from these folks that I cannot speak great volumes about are the very expensive stripper clips for the SKS. $120 for 100 of these things is very expensive, and 4 of the first 10 I randomly grabbed from the bulk packs were no good. Now to be fair, I have used approximately 20 of them and still have just those 4 that were junk; but a $1.20 each I expect to have a better percentage of usable product then I get from the "cheap" ones that are half the price.
