I have to agree. Did you buy all 10 from the same place? Recently? And how much? I'd complain, you can't be the first to have a problem. No way should 10 out of 10 magazines fail like that! And if they wouldn't work with me I'd find a way to even the score with them.
Glad to hear the PMAGs worked out for you. I've never had a bad one. I also have many good GI mags that work well too.
If you can't trade the crap mags I'd take them apart give them a good inspection. It would help if you had a GI mag that works. Compare the parts and figure out what's wrong. (Don't mix them up with the good one!) If the mag bodies are ok you might be able to put in Magpul Gen 3 followers and solve the problem. That would be about $3 per magazine.
The biggest issue with assembling an AR isn't so much getting the parts together right - it's getting the right parts together.
