I've got right around 30 USGI 20 rounders, they were given to me by a friend of mine when I bought my first AR. I've run then and they've never had an issue in my rifles or friend of mine's rifles when we have run them, and these mags were not babied and were run hard before I got them Just my experience, but quality mags are quality mags, doesn't matter who makes them as long as they run, if they don;t, well then you either fix them or ventilate them. Currently I have 30 rounders, 20 rounders, and even a couple C-product 40 rounders all of which have proven to be completely reliable.
